ComponentOne Licensing FAQ


Licensing is a mechanism used to protect intellectual property by ensuring that users are authorized to use software products.

Licensing is not only used to prevent illegal distribution of software products. Many software vendors, including GrapeCity, use licensing to allow potential users to test products before they decide to purchase them.

Without licensing, this type of distribution would not be practical for the vendor or convenient for the user. Vendors would either have to distribute evaluation software with limited functionality, or shift the burden of managing software licenses to customers, who could easily forget that the software being used is an evaluation version and has not been purchased.

ComponentOne has a licensing model based on the standard set by Microsoft, which works with all types of components. The licensing model is per developer, or per any machine that needs to build the application.

When a user decides to purchase a product, they receive a serial key. The serial key must be activated on the user's development machine (and up to two more machines, such as a laptop and build machine) in order to properly license any app built with ComponentOne controls.

When the user fully installs any product from the GrapeCity website, the licensing tools needed to activate the serial key will be installed. The user will be prompted to activate their serial key during the build process once their 30-day trial has expired.

When a licensed component is added to a .NET Framework form or page, Visual Studio obtains version and licensing information from the newly created component and will generate a licenses.licx file and add it to the project. The licenses.licx file contains the licensed component strong name and version information. The GrapeCity Visual Studio plugin (Under Tools) can be used to update this file and help resolve licensing issues.

When queried by Visual Studio, the .NET Framework component looks for licensing information stored in the system and generates an assembly resource file which contains the actual runtime license. For a Web Forms application, the run-time license may also be stored as an embedded resource in the App_Licenses.dll assembly, which must always be deployed with the application.

Later, when the component is created at run time, it obtains the run-time license from the appropriate assembly resource that was created at design time and can decide whether to simply accept the run-time license, to throw an exception and fail altogether, or to display some information reminding the user that the software has not been licensed.

When building .NET Core, Xamarin and UWP applications, the licensing is completely handled at build time. When queried by the NuGet build scripts, the component looks for licensing information stored in the system and generates a unique GrapeCity runtime license. If the license is valid, the component will generate a .gclicx file and include it with the build output. Only one .gclicx file is generated per application build. This file is not added to the project - it's only generated and distributed with the application output.

All ComponentOne Editions are designed to display licensing information if the product is not licensed. Applications will not run correctly if the license is missing or invalid after the 30-day trial has expired.

The following topics describe some of the licensing scenarios you may encounter.

Back to top >>


We try very hard to make the licensing mechanism as unobtrusive as possible, but problems may occur for a number of reasons. Here are the most common problems and their solutions.

Back to top >>


Q: How is ComponentOne Studio Enterprise licensed?

A: ComponentOne Studio and its Editions are licensed per developer per seat. This includes anyone who uses ComponentOne Studio components and controls to create and compile projects in Microsoft's Visual Studio. If someone wants to work with the code that a component or control has created, they need to have a license.

There are no limits on the distribution of applications—unlimited, royalty-free, run-time distribution. The licensing only affects design time.

Q: What is the difference between the Subscription and the License?

A: When you purchase the license, you receive a free one-year subscription that entitles you to the latest version of the software. The license is perpetual and does not expire; the subscription runs year to year. If you choose not to renew, you can still use the software as is; you just won't have access to the latest version.

Q: What is activation?

A: Activation is used by GrapeCity to verify the authenticity of the product key used to license the software and also to ensure that keys are only used to license an approved number of machines. The activation process does not collect any customer-specific information and protects the end user's privacy completely.

Q: Since I have a new (19-digit) license key, how do I use an older version of any ComponentOne product?

A: If you have a new 19-digit license key it must first be activated through the GrapeCity License Manager tool. Then if you'd like to use an older version of any ComponentOne product (version prior to 2020 v2), you can launch the legacy C1LicenseActivation tool and it will prompt you to install an old key that matches the new key's subscription time period. Then you will be able to use old versions of any product licensed within your subscription.

If you have a 28-digit license key you can use just the first 17 digits of your serial number to unlock older products through C1LicenseActivation. For example, for SE307AC-3G-XXXXXX-06-6WNWR1K you would use SE307AC-3G-XXXXXX.

Q: What is the difference in the serial numbers?

A: Beginning July 29th, 2020, GrapeCity distributes serial keys that are 19 characters long. These new keys are compatible with the GrapeCity License Manager activation tool. The old ComponentOne serial keys are 28 or 17 characters and are compatible with the C1LicenseActivation tool. The new serial keys can still be used with older versions of ComponentOne products, and vice versa, so long as you use the correct activation tool for the serial key you are trying to activate.

Q: Can I still license new controls with an old serial number?

A: Yes. As long as your serial number reflects an active subscription, you can enter it into the C1LicenseActivation tool and successfully license your controls.

Q: I have a serial key between 2019 v2 and 2020 v1, will I need a new serial key to update 2020 v2?

A: No. You can continue to use all future versions within your subscription without issue. The controls will first check for a new license, and if one is not found, they will check for a valid old license. The serial key would still need activated on the developer's machine using C1LicenseActivation if it was purchased before July 29th, 2020.

Q: When I tried to activate my serial key, I get a message like "Hit Machine Count Limit", how can I request additional activations?

A: The usage of this serial key has been exceed the limit. Please try to deactivate it on a different machine, which does not need it any more, and then try to activate it on this machine again. If the problem still occur, please visit and submit a re-activation request, we will handle with your request soon.

Q: When I tried to activate my serial key, I get a message like "Hit Frequency Limit", how can I activate my license?

A: The serial key has been activated too frequently. A serial key can only be deactivated and reactivated up to 9 times within 24 hours. Please try it after 24 hours. If the problem still occur, please visit and submit a re-activation request, we will handle with your request soon.

Q: I received an error that my serial number is invalid. What should I do?

A: Click on the About button for the control you're trying to license and identify the version number. If the control is a 2007 v3 control or earlier, then you should only enter the first 17 characters of your serial number. If it is 2008 v1 or later, you should your full serial number (if your serial number is from 2008 v1 or later it will be 28 characters; otherwise it will be 17). If you're still experiencing problems, please contact your sales representative for assistance. The GrapeCity Sales team can be reached at 1-800-858-2739. Your sales representative can determine if your serial number is valid and help you to get a valid serial number or further assistance if your serial number is valid.

Q: I have an expired license on my machine and my controls did not activate properly. What do I do?

A: Run the license removal tool. Files are located here. This removes the existing license. Once this is done, you can activate your studio by pressing the Activate button in the About Box of any ComponentOne Studio control.

Q: The license removal tool did not find any licenses. What do I do next?

A: You will need to manually deactivate your controls. To do this, go into the About box of any .NET 2.0 control, and click deactivate. Enter your new license key into the appropriate boxes and click OK.

Q: Is there a limit to the number of activations I can use for a single license?

A: The limit is three (3) machines per license. Allowed installations include any combination of a primary machine (desktop), backup machine (laptop), build machine, or test machine.

Q: Is any personal information collected/submitted during the activation process?

A: No. No personal information is collected.

Q: What happens if I have used all of the activations I am allowed and I need to activate another computer?

A: You can deactivate on one machine in order to free up an activation for a different machine. A serial key can only be activated on 3 different machines and up to 9 times within 24 hours. If you cannot deactivate any of your current computers, you will need to purchase additional licenses or request an additional activation. You may request an additional activation from the following site, by clicking Reactivation:

Q: I was previously given a multi-year license, what do I do now?

A: You'll need to receive a new license key. Please contact your sales representative for assistance. The GrapeCity Developer Tools sales team can be reached at 1-800-858-2739.

Q: I want to activate products on a machine that does not have an internet connection. What do I do?

A: You can activate an offline machine through another machine that is connected to the internet. This is known as offline activation.

If you have a new key purchased or renewed after July 29th, 2020, you can activate an offline machine from the following site, by clicking Activation (or Deactivation for offline deactivation):

If your key is from before July 29th, 2020, you can activate by phone, e-mail, or online. All three processes are described here: Once you've completed your manual activation, you'll receive an Activation Code. Enter the serial number of your product and the authentication number you received into the Activation Wizard, and complete the process.

Q: If I am redistributing ComponentOne Studio controls in my application, do my users need to use activation?

A: No. Only the developers who are installing ComponentOne Studio controls for use in development projects need to activate their controls.

Q: What is the impact of activation on UAC (User Account Control)?

A: Licensing procedures invoked by ComponentOne Studio setups will always request activation so that all controls will be licensed. Running the ComponentOne Studio setup will require Administrative privileges during execution. For Windows Vista operating systems and higher, a prompt requesting Administrative privileges will be given if the Vista UAC is turned on and the process starting the setup program does not already have Administrative privileges.

ActiveX Edition Licensing

ActiveX Edition licensing is handled transparently by .NET in C#.NET and VB.NET, so special consideration is not required when adding ActiveX controls to a form or user control in .NET. However, if you put an unlicensed version of the control on a form, or you wish to change licenses, you must remove the old control and add it back again to get the new licensing. The behavior is identical to that of a VC++ project using an ActiveX control.

For information on dynamically adding ActiveX controls that require run-time licenses, see the Microsoft Support site. All ComponentOne Studio Editions are designed to display licensing information if the product is not licensed. None will throw licensing exceptions and prevent applications from running.

Visual Studio 2017 version 15.5.0

released on December 4, 2017

New Features in 15.5

Visual Studio IDE

Setup and Install
  • Installer now generates a Windows restore point during installation.
  • Add and Remove Programs now has entries for each Visual Studio installation. Visual Studio Installer now supports modify and uninstall for each entry.
  • Installing from an offline layout no longer requires installing intermediate certificates on a disconnected computer.
  • We added reliability and cancellability improvements in the install and update process.
Updated Error Dialog

We updated the error dialog to display more information to help solve installation problems using potential solutions from the Visual Studio Developer Community. (Figure 1).

  • Reduced load times of large C# and Visual Basic projects.
  • Reduced time to switch configurations between debug and release.
  • Reduced time to add, remove, and rename files and folders in .NET Core projects.
  • Deprecated Lightweight Solution Load (LSL) because solution load time without LSL has been reduced.
Connected Services
  • We updated the Azure Storage service provider to support ASP.NET Core projects that target .NET Core.

Team Explorer Updates

The latest updates to Team Explorer have been inspired by your feedback on UserVoice.

You can now work with Git submodules and worktrees, and configure and in Team Explorer. Visual Studio now treats Git submodules and worktrees like normal repos. Just add them to your list of Local Repositories and get coding!

Please note that for submodules, you still cannot do any action that requires multi-repo support (such as viewing a file in the parent repo and a file in the submodule at the same time).

Additionally, it's now easier to set your default Git behavior to prune on every fetch and to rebase on every pull. Pruning on every fetch removes local tracking branches that no longer exist on the server and helps you keep your branches list clean and up to date. Rebasing on every pull keeps your commit history linear and easier to follow. You can find these options in Global and Repository Settings.

.NET Core and ASP.NET Core Security Advisories

Microsoft has released security advisories for .NET Core and ASP.NET Core. Details can be found in corresponding announcements in the .NET Core and ASP.NET Core repos. Please note the following information:

  • CVE-2017-8585 Malformed Certificate can cause Denial of Service: There is a security vulnerability in .NET Core 1.0, 1.1 and 2.0 where a malformed certificate or other ASN.1 formatted data could lead to a denial of service through an infinite loop on Linux and macOS. System administrators are advised to update their .NET Core runtimes to versions 1.0.8, 1.1.5 and 2.0.1. Developers are advised to update their .NET Core SDK to version 2.0.3 or 1.1.5.

  • CVE-2017-8700 CORS bypass can enable Information Disclosure: There is a security vulnerability in ASP.NET Core 1.0 and 1.1 where Cross-Origin Resource Sharing (CORS) can be bypassed, leading to information disclosure.

  • CVE-2017-11879 Open Redirect can cause Elevation Of Privilege: There is a security vulnerability in ASP.NET Core 2.0 where an Open Redirect exists, leading to Elevation Of Privilege.

  • CVE-2017-11770 Denial Of Service Vulnerability: There is a security vulnerability in ASP.NET Core 1.0, 1.1 and 2.0 when the application is hosted through Windows Http.Sys where a malformed request can lead to a Denial Of Service.

New projects created with ASP.NET Core 1.0, ASP.NET Core 1.1 and ASP.NET Core 2.0 now use package versions that include the above security updates. For existing projects, users can update their packages to newer versions using the Manage NuGet Packages dialog.

MSVC Compiler Toolset

In Visual Studio 2017 15.5, the MSVC compiler toolset in Build Tools has been updated to version to 14.12, which is compatible with the 15.4 version 14.11 toolset. In the event that you encounter an issue compiling your code after upgrading to Visual Studio 2017 15.5, you can force installation of the 14.11 toolset side-by-side with the 14.12 toolset. The Visual Studio 2017 15.4 toolset (14.11) can be selected under the Individual Components tab, after installing the C++ Desktop workload.

What's New in the C# Compiler

The C# compiler now supports the 7.2 set of language features including:

  • Support for the type being used throughout Kestrel and CoreFX through the modifier.
  • modifier: Enforces that all members of a struct are . This adds a layer of correctness to code and also allows the compiler to avoid unnecessary copying of values when accessing members.
  • parameters / returns: Allows for unmodifiable structs to be safely passed and returned with the same efficiency as modifiable values.
  • access modifier: Restricts access to the intersection of and .
  • Non-trailing named arguments: Named arguments can now be used in the middle of an argument list without the requirement that all following arguments are passed by name as well.

Visual Studio Tools for Xamarin

This release contains updated support for the Xamarin SDKs for iOS and Android:

Live Run Current View

Building XAML-based user interfaces just got even easier with our new Live Run Current View feature (Figure 2). As you build out your user interface, see it come to life as you type in the Android emulator, without having to save, compile, or redeploy the app.

Xamarin Live Player

The Xamarin Live Player enables developers to continuously deploy, test, and debug their apps, directly on iOS and Android devices. After downloading the Xamarin Live Player app (available in the App Store or on Google Play), you can pair your device with Visual Studio and begin building mobile apps using just Visual Studio and your mobile device. Optimized for Xamarin.Forms, you can now modify their XAML and see the changes reflected in moments on your device without having to compile or wait for a full deploy. This release brings numerous enhancements to our Xamarin Live functionality, including:

  • Smarter Debug and Live Run: The Live Player now automatically adjusts your start-up project to the correct platform when debugging to the Xamarin Live Player (Figure 3). For example, if iOS is selected and the Live Player device that is paired is a Google Pixel, the IDE will recommend you change your start-up project to Android.
  • Deployment Status: You can now track the status of a "Debug" to the Xamarin Live Player with deployment statuses in the status bar.
  • Console and Error Window Integration: Output logged within the app now appears within the Console window, and errors will appear in the Errors window in Visual Studio.
  • Live Run Context Menu and Keyboard Shortcut: We wanted to make it easy to instantaneously visualize your XAML UI, so we added a context menu and keyboard shortcut to make previewing your XAML pages fast and easy.
  • Live Run Document Switching: When building out UIs, it's common to switch between different XAML documents. Changing the active document in Visual Studio automatically live runs whatever XAML page you have open, so you can easily switch back-and-forth between different pages and have them reflected on your device instantaneously.

File -> New Project -> Mobile App(Figure 4) just got easier with updates to the cross-platform template wizard for iOS, Android, and Windows apps, including:

  • .NET Standard Support - You can now create a new cross-platform Xamarin app that uses .NET Standard 2.0 as a code sharing strategy.
  • Target Platforms Checkbox - Select what platforms you care about at File -> New.
  • - All templates now default to using , a new easy way to manage NuGet packages in your Xamarin apps.
  • Unfold performance enhancements - Templates should now unfold much faster than before. In the most extreme cases, you may see up to a 40x improvement in unfold time.
Remoted iOS Simulator

The Remoted iOS Simulator provides you with an easy way to debug and test iOS apps on the simulator entirely from Visual Studio on Windows. It supports everything that the iOS Simulator on Mac can do and even more - including multi-touch support! Beginning in Visual Studio 2017 version 15.5, the Remoted iOS Simulator is now available in all Visual Studio Editions, including the free Community Edition.

Xamarin Android SDK Manager

Managing your Android SDKs just got easier with the new Xamarin Android SDK Manager. You can use the new SDK Manager by going to Tools -> Android -> Android SDK Manager in Visual Studio.

F# Tooling Improvements

In the Visual Studio 2017 15.5 release, we focused on F# tooling support for .NET Core SDK projects. The following are now supported:

  • You can create new .NET Core console apps, .NET Standard libraries, and .NET Core unit test projects from File > New Project.
  • We added support for existing .NET Core and .NET Standard projects.
  • We added support for existing .NET Core SDK projects that target a .NET Framework version.
  • Project-to-project references are supported.
  • We added support for Web SDK projects (e.g., F# ASP.NET Core projects or a project using the Giraffe template).
  • You can now right-click Publish tooling with Web SDK projects.
  • Autogenerating a CI/CD pipeline with Visual Studio Team Services tooling is supported.

There have also been quite a few improvements to the Visual F# tooling that are not focused on .NET Core SDK projects. They include:

  • Go to Definition from F# to C#, by Saul Rennison and Vasily Kirichenko.
  • Colorization for Blue (Extra Contrast) theme, by Microsoft and Vasily Kirichenko.
  • Property pages now auto-size correctly on different monitors.
  • Smart auto-indent for new lines when indentation is set to "Smart", by Duc Nghiem Xuan.
  • Auto-deindentation for closing brackets when indentation is set to "Smart", by Saul Rennison.
  • Enumeration fields are now able to be seen as symbols in tooltips, Find All References, Go to All, and Inline Rename, by Vasily Kirichenko.
  • XML doc comments that are separated by newlines are not prepended to the current XML doc comment in hovers, by Vasily Kirichenko.
  • The XML documentation for the ref keyword has been corrected by CHBen.
  • Multiple bug fixes and performance improvements.

Please file any issues you find on our GitHub repository.

Changes in F# Setup

We have changed the way that you acquire F#:

  • If you install a Workload that requires .NET Core 2.0, it also installs F# language support by default. The .NET Core, ASP.NET, and Azure workloads now do this.
  • The "F# language support" checkbox in the .NET desktop development, Data storage and processing, and Data science and analytical applications workloads have been renamed to "F# desktop support".

F# 4.1 Compiler Improvements

There are a number of bug fixes in the F# 4.1 compiler with this release:

  • Improvements to PDB generation in the F# compiler, fixing five known issues in debugging F# dating back to 2014.
  • A fix for record fields being incorrectly resolved by the compiler, by Vasily Kirichenko.
  • now properly waits for cancellation to finish, by Matthias Ditrich.
  • Assembly references are now created when a type is used in an attribute only.
  • Single-case struct discriminated unions with the same case name are no longer silently converted to an object type.
  • A possible endless async loop on . Receive has been fixed.

Visual C++ Improvements

You now have the ability to import existing CMake projects and cache configurations into the IDE through File > Open > CMake.

Open Folder Support for ARM Online Compiler Exports

Choose the option in the Linux C++ workload for Embedded and IoT projects and you can edit and compile projects targeting ARM microcontrollers. We support opening projects exported as GCC from the ARM online compiler that can then be cross-compiled locally from within Visual Studio. For more information, see our blog post on Visual C++ for ARM development.

Remote Tasks

Open folder now supports remote tasks. These are tasks that execute on a remote system over Secure Shell (SSH). These tasks can also be configured to copy files to the target machine for doing things like compiling code with make on a Linux system. To learn more, see our blog post on using remote tasks in Visual Studio.

Improvements for the Standard Template Library

The Open Standards website holds a number of pages for groups producing open standards. We added these improvements to the Standard Template Library regarding the C++17 standard:

  • : P0005R4 recommends adopting the function binder from the Library Fundamentals TS v2 as a replacement for the old negators, and .
  • Rewording : P0033R1.
  • Deprecating Vestigial Library Parts: P0174R2. A number of features of the C++ Standard library have been surpassed by additions over the years, or we have learned do not serve their intended purpose as well as originally expected. This paper proposed deprecating features where better, simpler, or clearer options are available.
  • Removing Allocator Support In : P0302R1. The class template std::function has several constructors that take an allocator argument, but the semantics are unclear, and there are technical issues with storing an allocator in a type-erased context and then recovering that allocator later for any allocations needed during copy assignment. Those constructors should be removed.
  • Fixes for : P0358R1. The new wording for is proposed, that amongst other improvements, provides support of propagation of value category in case of wrapper invocation.
  • , : P0414R2. Merging changes from Library Fundamentals to C++17.
  • Fixing for Arrays: P0497R0. Fixes to support for arrays.
  • Deprecating : P0521R0. Proposed Resolution for CA 14 ().
  • Deprecating : P0618R0,
  • Removing Dynamic Exception Specifications: P0003R5. Dynamic exception specifications were deprecated in C++11. Removing the feature from C++17, while retaining the (still) deprecated throw() specification strictly as an alias for noexcept(true).
  • Splicing Maps and Sets: P0083R3. This design allows splicing operations of all kinds, moving elements (including map keys) out of the container, and a number of other useful operations and designs. It is an enhancement to the associative and unordered associative containers to support the manipulation of nodes. This is a pure addition to the Standard Library.
  • Clarifying : P0508R0. The associative containers with unique keys, and the unordered containers with unique keys have a member function insert that returns a nested type . That return type is a specialization of the type specified in this section.
  • Inline Variables for the STL: P0607R0.
Visual C++ Compiler Improvements

The Visual C++ compiler supports about 75% of the C++17 features, including structured bindings, lambdas, , inline variables, fold expressions, hexfloat literals, and adding to the type system. These are available under the switch. The conformance mode includes partial support for two-phase name lookup and improved pack expansion support for variadic templates. Additionally, mode has been added as new Language drop-down menu in the project properties for C++ projects.

Visual C++ Optimizer Improvements

The C++ code generation team has made improvements to existing compiler optimizations, and added new optimizations in the 15.5 release.

Select linker improvements:

  • You will experience new and faster implementation: up to 9% link time speedups.
  • We made fixes to incremental linking. Incremental linking will never be slower than full linking.

Select improvements to existing optimizations:

  • We improved vectorizer heuristic for conditional expressions.
  • We enhanced optimization.
  • We made improvements to loop unrolling.
  • We improved float min/max codegen.

Select new optimizations:

  • We improved and eliminated redundant (and partially redundant) instructions to SSA Optimizer.
  • We optimized vectorization of conditional scalar stores.
  • We combine calls and to .

Visual C++ supports Intel's AVX-512, including the Vector Length instructions that bring new functions in AVX-512 to 128- and 256-bit wide registers.

We are shipping over 20 new C++ Core Guidelines checks in C++ code analysis. These checks cover smart pointer correctness, correct use of global initializers, and flagging uses of constructs like and .

Some warning numbers you may find in 15.3 are no longer available in 15.5. These warnings were replaced with more specific checks.

Built-in Support for Google Test and Boost.Test Framework

Write, discover, and run your Google Test and Boost.Test unit tests in Visual Studio. By default, the Test Explorer now supports the Google Test and Boost.Test frameworks. If you are upgrading from a previous Visual Studio installation, open the Visual Studio Installer, click "Modify" on your Visual Studio instance, and check the "Test Adapter for Google Test" and "Test Adapter for Boost.Test" boxes under "Desktop development with C++". Easily create a new Google Test project: select File > New > Project > Visual C++ > Test > Google Test.

For more information please refer to the How to use Google Test for C++ in Visual Studio and How to use Boost.Test for C++ in Visual Studio pages on Microsoft Docs.

Visual Studio Web Tools

  • Razor syntax formatting has been improved.
  • We improved the experience for publishing ASP.NET applications to Azure Virtual Machines.

Docker Container Tooling

  • Visual Studio's tools for Docker containers now support multi-stage Dockerfiles, to streamline the creation of optimized container images.
  • If you are running Visual Studio on a machine running Windows 10 version 1709 or Windows Server version 1709, your container images will utilize Windows Server version 1709 by default. You can change this by editing the Dockerfile. Please note that container images that utilize older versions of Windows will only run on Windows 10 version 1709 and Windows Server version 1709 in Hyper-V isolation mode. For more details, please see Windows Container Version Compatibility page.
  • By default, Visual Studio will automatically pull, build, and run the necessary container images in the background when you open a project that has Docker support. You can disable this through the Automatically start containers in background setting in Visual Studio.

TypeScript/JavaScript Improvements

Angular 2 Support

Angular2 developers can now see errors, completions, and code navigation in inline templates and .ngml template files. See the sample repo for an overview and instructions.

Performance Improvements

We added an Only analyze projects which contain files opened in the editor checkbox under the JavaScript/TypeScript Text Editor Project Options page. This option will improve performance and reliability in large solutions. Note that when this box is checked, you will need to perform a Solution build to see a complete list of TypeScript errors in all files.

We fixed an issue that caused the TypeScript/JavaScript language service to use more memory than intended and could cause the wrong version of TypeScript to be loaded in multi-project solutions.

Windows Communication Foundation (WCF) Tools

The WCF Web Service Reference connected service provider (Figure 5) is now part of Visual Studio 15.5.

To use this tool, right click on the Dependencies project item in your .Net Core project and select the Add Connected Service option, and enter the address of the web service that you want to generate code for. The generated WCF client proxy code is saved into a C# file that is automatically added to your project. This allows your .NET Core based code to easily communicate with the web service.

Please visit the WCF Web Service Reference release notes in GitHub for more details.

Debugging and Diagnostics

Debug In-production Apps with the Snapshot Debugger

You can now use Snappoints and Logpoints to debug against ASP.NET and ASP.NET Core applications running in Azure App Services with minimal impact to the app.

  • Set Snappoints (Figure 6) to capture the state of your app, including Locals, Watches, and the Call Stack. Unlike breakpoints, your app does not stop when a Snappoint is hit.
  • Use Logpoints (Figure 7) to log new messages from your app without needing to add code or redeploy your application.
Embedded Source and Embedded PDB Support

With Embedded Source, the Visual Studio Debugger can now extract and use source files for managed binaries directly from the PDB files. Combine Embedded Source with Embedded PDB to create fully standalone debuggable binaries. Learn more about using the /embed compiler switch.

You can also now debug using Edit and Continue for managed code when building with Embedded PDBs.

Step-back While Debugging with IntelliTrace

With the new IntelliTrace Step-back debugging feature, IntelliTrace automatically takes a snapshot of your application on each breakpoint and debugger step. This enables you to go back to previous breakpoints or steps and view the state of the application as it was in the past.

This feature is available on Windows 10 Anniversary Update and above, and currently supports debugging ASP.NET, WinForms, WPF, managed console apps, and managed class libraries (Figure 8). To enable the feature, go to Tools > Options > IntelliTrace settings and select IntelliTrace events and snapshots.

Accessing Azure Resources from Visual Studio with Conditional Access Enabled

Visual Studio now supports access to Azure resources that have conditional access enabled that requires you to authenticate with 2FA, even if your account itself does not require 2FA. Previously, if your account required 2FA to sign in, Visual Studio would prompt for 2FA and you could then access any resources that required 2FA; but if your account did not require 2FA, Visual Studio would fail to access those 2FA resources.

Now, when accounts do not require 2FA but resources do, you may authenticate your account within Visual Studio without 2FA, and when you first try to access an Azure resource that requires 2FA, Visual Studio prompts you to re-authenticate and requires 2FA to enable access to your resource.

Office Tooling Support for Office in the Windows Store

Office Web Add-in projects and VSTO Projects now support development with Office in the Windows Store. You can create, build, debug, and publish Web Add-in projects and VSTO projects using Office in the Windows Store.

  • The Fall Creators Update (version 1709) for Windows 10 or Windows Server 2016 is required to use the Office Tooling with Office in the Windows Store.

Visual Studio Tools for Unity

  • Unity projects are now automatically reloaded in Visual Studio when you add or remove a script from Unity.
  • Fixed .Player project generation when working on a UWP game with the IL2CPP/.NET 4.6 backend.
  • Introduced an option to use the Mono debugger shared by Xamarin and Visual Studio for Mac to debug the Unity Editor.

Live Unit Testing

  • Live Unit Testing's builds are now out-of-process improving memory utilization in Visual Studio.

Windows Packaging

We added support in the packaging project to include UWP applications and components that helps to take advantage of the latest Windows 10 capabilities from your existing desktop applications. To include a UWP components you can to the UWP application (Figure 9).

You can use the store package wizard to generate the files you need to submit your Desktop Bridge application to the store, as with existing UWP projects.

Microsoft Security Advisories for .NET Core

  • CVE-2018-0786 Security Feature Bypass in X509 Certificate Validation Microsoft is releasing this security advisory to provide information about a vulnerability in the public versions of .NET Core 1.0 and 1.1, and 2.0. This advisory also provides guidance on what developers can do to update their applications correctly. This security advisory is also applicable to .NET native for UWP.

    Microsoft is aware of a security vulnerability in the public versions of .NET Core where an attacker could present a certificate that is marked invalid for a specific use, but a component uses it for that purpose. This action disregards the Enhanced Key Usage tagging.

    The security update addresses the vulnerability by ensuring that .NET Core components completely validate certificates. System administrators are advised to update their .NET Core runtimes to versions 1.0.9, 1.1.6 and 2.0.5. Developers are advised to update their .NET Core SDK to version 2.1.4 or 1.1.7.

  • CVE-2018-0764 Denial of Service when parsing XML documents Microsoft is releasing this security advisory to provide information about a vulnerability in the public versions of .NET Core 1.0 and 1.1, and 2.0. This advisory also provides guidance on what developers can do to update their applications correctly.

    Microsoft is aware of a Denial of Service vulnerability in all public versions of .NET core due to improper processing of XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Core application.

    The update addresses the vulnerability by correcting how .NET core handles XML document processing. System administrators are advised to update their .NET Core runtimes to versions 1.0.9, 1.1.6 and 2.0.5. Developers are advised to update their .NET Core SDK to version 2.1.4 or 1.1.7.
