What's New in Visual Studio 2019 version 16.7

Support Timeframe

Visual Studio 2019 version 16.7 is the third supported servicing baseline for Visual Studio 2019. Enterprise and Professional customers needing to adopt a long term stable and secure development environment are encouraged to standardize on this version.  As explained in more detail in our lifecycle and support policy, version 16.7 will be supported with fixes and security updates for one year after the release of the next servicing baseline.

In addition, now that version 16.7 is available, version 16.4, which was the last servicing baseline, will be supported for an additional 12 months and will go out of support in October 2021. Note as well that versions 16.5 and 16.6 are no longer under support. These intermediary releases received servicing fixes only until the next minor update released.

You can acquire the latest most secure version of Visual Studio 2019 version 16.7 in the downloads section of my.visualstudio.com.  For more information about Visual Studio supported baselines, please review the support policy for Visual Studio 2019.

In This Release of Visual Studio 2019 version 16.7.0


C++

  • Our remote C++ support now supports a wider range of Linux distros and shells, including sh, csh, bash, tsch, ksh, zsh, and dash. You can override the choice of a shell for a remote connection by modifying the new "shell" property via ConnectionManager.exe. This support has been tested with both MSBuild-based Linux projects and CMake projects targeting a remote Linux system or WSL.
  • You can now use Ninja (a build system that evaluates incremental builds very quickly) to improve incremental build times for MSBuild-based Linux projects. You can opt into this feature by setting "Enable Incremental Build" to "With Ninja" in the General Property Page. Ninja (ninja-build) must be installed on your remote Linux system or WSL.
  • New C++20 Standard Library features have been implemented. Please refer to the STL Changelog on GitHub for a detailed list.
  • You can now edit and set default remote SSH connections in the Connection Manager. This means you can edit an existing remote connection (e.g. if its IP address changed) and set default connections to be consumed in CMakeSettings.json and launch.vs.json. Remote SSH connections allow you to build and debug C++ projects on a remote Linux system directly from Visual Studio.

  • Enhanced IntelliSense support for Clang on Windows (clang-cl) in Visual Studio. The clang include path now includes the clang libraries, we've improved in-editor squiggle display when using the std library, and we've added support for C++2a in clang mode.
  • You can now try out underlining code errors and see more suggested quick fixes in C++ projects. Enable this feature under Tools > Options > Text Editor > C/C++ > Experimental > Set 'Disable Experimental Code Linter' to false. Learn more on the C++ Team Blog.

  • We've added four new code analysis rules to incorporate additional safety features into C++: C26817, C26818, C26819, and C26820.
  • We've added first-class support for debugging CMake projects on remote systems with gdbserver.
  • Find memory corruption errors easily with an experimental implementation of AddressSanitizer for C++ in Visual Studio, now available for x64 native projects. We also now support the use of debug runtimes (/MTd, /MDd, /LDd).
  • IntelliSense now has basic support for Concepts, designated initializers, and several other C++20 features.
  • .ixx and .cppm files are now recognised as C++ and will be treated as such by the syntax highlighter and IntelliSense.

Define playlists dynamically

You can now define playlists dynamically based on Project, Class, or Namespace. This means you can configure a playlist to include everything in a certain project/class/namespace; any new test added to that group will automatically be included in your playlist!

  • Create a playlist by right clicking on a project, namespace, or class grouping in the Test Explorer.
Test Explorer: Create a playlist
Test Explorer: Create a playlist
  • Edit what groups are included in the playlist by clicking on the edit button in the tool bar. Check boxes will appear. Edit groups as desired.
Test Explorer: Edit a playlist
Test Explorer: Edit a playlist
  • Instead of being a static list of tests these playlists dynamically update based on rules. If you want to better understand what rules are generating your dynamic playlist, save the playlist file to disk with the save button and view the rules generated in the xml.
PlayList file dynamic rule set

  • You can continue to include/exclude individual tests and the playlist will be able to either update its dynamic rules or switch back to keeping track of tests as a static list. You can also use traits to define a dynamic group by editing the playlist xml file directly.

Git Productivity

Toggle on the 'New Git user experience' Preview Feature in Tools | Options | Environment to use this experience.

  • Create a new Git repository, starting from any folder or a brand new folder
  • Save and close an open folder or solution before starting a new clone operation

Resolve merge conflicts with a Git focused merge editor using:

  • An info bar in files containing merge conflicts that prompts you to open the merge editor
  • More informative titles and captions, and less clutter in the merge editor
  • Diffs within conflicts that align matching lines, show word level differences, and display visible whitespace when it is the only difference.
  • Two-way merges for file level add/add conflicts
  • The ability to resolve all conflicts to one side or the other with a single click
  • A toggle to focus on just conflicts, ignoring non-conflicting differences

Local Process with Kubernetes

Local Process with Kubernetes
Local Process with Kubernetes

Local Process with Kubernetes allows you to write, test and debug your .NET code on your development workstation while connected to your Kubernetes cluster with the rest of your application or services. By connecting your development workstation to your cluster, you eliminate the need to manually run and configure dependent services on your development machine. Environment variables, connection strings and volumes from the cluster are available to your microservice code running locally. There is no need for extra assets, such as a Dockerfile or Kubernetes manifests. Run, debug, and test your .NET code as you normally would.

To enable Local Process with Kubernetes, go to Tools > Options > Envrionment > Preview Features and select "Enable local debugging for Kubernetes services".

  • You can now add a parameter within the Change Signature dialog. Place your cursor within the method’s signature. Press (Ctrl+.) to trigger the Quick Actions and Refactorings menu. Select Change signature. The following dialog will open where you can now select Add to add a parameter. Once you select Add, the new Add Parameter dialog will open. The Add Parameter dialog allows you to add a type name and a parameter name. You can choose to make the parameter required or optional with a default value. You can then add a value at the call site and choose a named argument for that value or you can introduce a TODO variable. The TODO variable puts a TODO in your code so you can visit each error and go through each call site independently and decide what to pass. For optional parameters you have the option to omit the call site completely.

  • Analyzer authors can now use CompletionProviders for IntelliSense completions when shipping their analyzers with NuGet. Before, library authors would have to create a separate VSIX since CompletionProviders was only available in VSIX. Now library authors can implement IntelliSense completions in the NuGet package where their analyzers are, and they don’t need to do it separately. Completion providers implemented in NuGet packages will also provide suggestions specific to individual projects and will automatically work in each IDE supporting the feature.

Razor

Try out the new experimental Language Server Protocol (LSP) powered Razor editor with all Razor files (.cshtml/.razor) by selecting the Enable experimental Razor editor preview feature.

Test Explorer

Run/Debug All Tests In View have been added to the Test Explorer. These commands replace where the Run All Tests and Debug All Tests commands appeared in the Test Explorer. This change clarifies that these commands honor the filters of the Test Explorer so that only tests visible in window are run. This includes both column filters and search box filters.

Test Explorer Run/Debug All Tests in View commands
Test Explorer Run/Debug All Tests in View commands

The Global Run/Debug All commands will now only appear in the top-level Test menu. They are no longer included in the Test Explorer toolbar or context menu of any test window view. When triggered from the Test Explorer, the Analyze Code Coverage for All Tests now applies to the test window views as well.

Short-cut Keys:

  • Ctrl R, A - Run All Test - Global command always runs all tests
  • Ctrl R, V - Run All Tests In View - Only a valid command when a test window (Test Explorer, Playlist, Live Unit Testing Window) are active windows
  • Ctrl R, Ctrl A - Debug All Test - Global command always debugs all tests
  • Ctrl R, Ctrl V - Debug All Tests In View - Only a valid command when a test window (Test Explorer, Playlist, Live Unit Testing Window) are active windows

XAML Tools (WPF, UWP & Xamarin.Forms)

XAML Hot Reload:

  • In-app Toolbar Improvements: We have further refined the in-app toolbar experience that is part of the XAML Hot Reload tooling workflow for WPF & UWP. Changes include a shorter toolbar so that it no longer covers the running application, and a change in the collapse mechanism which when clicked will now collapse the XAML Hot Reload text first, then collapse the bar fully on the second click.

XAML Designer:

  • Expanded Design-time Data Support for WPF & UWP: In this release we are introducing a new design-time data feature for WPF .NET Core and UWP developers. This new capability will extend the current list of accessible design-time properties through the use of the d: prefix. This feature will be familiar to Xamarin.Forms developers, as it makes available the same approach of using a “d:” prefix to indicate a property that should only be rendered at design-time and never gets compiled into the running app making it very safe to use for design time UI validation. In this release we support all the out-of-the-box controls for WPF and UWP and plan to support 3rd party and custom controls in future releases.
  • XAML Designer Refresh Button: We have added a refresh button to the XAML designer, this new icon can be found in the bottom-left icon area near the zoom level indicator. This refresh action does the equivalent reset of closing the designer view and re-opening it for the rare situations where this is required to resolve a rendering issue. This feature is available for WPF .NET Core and UWP developers.

XAML Code Editor:

  • Color Visualizer: We have further refined our new color visualizer in the XAML code editor for WPF .NET Core, WPF .NET Framework and Xamarin.Froms projects. In this release we have added support for visualizing colors coming from resources, which was previously not supported in the last preview.

Show Toolbox items from a NuGet package without having a package reference

Many control library authors want their controls to be seen in the Toolbox even when the current project hasn't referenced the library yet, as this helps with discoverability. WPF .NET Framework SDKs have historically accomplished this using registry entries, but this is not supported by .NET Core. For WPF .NET Core, Toolbox can now be populated with controls from VisualStudioToolsManifest.xml files found within WPF .NET Core NuGet packages in NuGet fallback folders. For more details, see the documentation in the XAML Designer Extensibility GitHub repo.

Windows Forms

Windows Forms Designer for .NET Core

The Windows Forms designer for .NET Core projects is now available. To enable the designer in Visual Studio, go to Tools > Options > Environment > Preview Features and select the Use the preview Windows Forms designer for .NET Core apps option.

In this release the following controls are now supported along with other improvements:

  • UserControl and custom controls infrastructure
  • TableLayoutPanel
  • Fundamentals for third-party controls support
  • Fundamentals for data binding support
  • Improvements in designer interaction with the TableLayoutPanel
