Comparing Files

In response to this highly upvoted ticket in Developer Community, you can now compare files in Solution Explorer. You can right-click a file in Solution Explorer and use the context menu option “Compare with…” to open File Explorer to select an item for comparison. Alternatively, you can use the context menu option “Select for Compare,” then right-click on another item in Solution Explorer and select “Compare with the selected file.” Either option will launch our compare view.

This is just the start of improvements we’re planning to make for diffing experience, so please share your feedback about this feature here.

Multi-branch Graph & Git Repository Improvements

The power of Git really comes alive when you can see multiple branches at the same time to understand how the branches are related and inform operations. We’ve implemented the first version of this suggestion, to enable visualizing multiple branches in the same graph, along with other Git Repository improvements. When opening the Git Repo window, you start in the single branch view, and you can click on any branch to add that branch and its commits to the graph. In the below scenario, you can easily visualize new-branch-3 in order to cherry pick the bug fix commit onto New-branch-2, the currently checked out branch. You can also use the hover eye icon to toggle multiple branches on and off in the graph.

Visualize multiple branches and execute cross branch operations.

Additionally, you can:

  • Get more space to view the graph and history table by collapsing the Branches panel using the highlighted collapse icon in the upper right corner.
  • Maximize your commit details using the highlighted expand icon in the upper right corner.
  • See avatars for your author in Azure DevOps repos.
  • See the graph updates more smoothly when switching which branches are in view.

New Git Repo window lets you collapse selectors & expand commit details.

Known limitations: When you toggle a new branch on in the graph, the branch head may not be immediately visible. However, you can scroll to the branch head by selecting between items that have already been toggled on.

This feature is on in preview under the flag “Git Repository multiple branch history” in Tools > Options > Preview Features, and we have many improvements on the way. Please let us know what you think in this survey.

Copy and Trim Indentation

If you’ve ever copied code from Visual Studio to another program (Outlook, Teams, Slack, etc), you’ll like this feature. Visual Studio now automatically fixes indentation for you when you copy code from Visual Studio and paste it in another program.

Try out this feature by enabling it in Tools > Manage Preview Features > “Copy and Trim Indentation”. If you have feedback to share with us about this feature, let us know here.

All-in-One Search Enhancements

We’ve tackled known accuracy and performance issues resulting in several enhancements including:

.NET and Cloud development

IntelliTest Support for .NET 6+ and NetStandard

Now available in Preview, once enabled, the editor context menu “IntelliTest (Preview)” will be enabled in net6 and netstandard code files.

Create Project will create a compatible test framework project into which generated tests can be saved and subsequently run using Test Explorer or through the CLI. This will create stubs of methods, but not actually probe your code to create asserts. This can be useful by itself to create a lattice into which you would inject your own code, but typically it’s a placeholder and provides a preview of all the methods supported in your code file. It’s not necessary to create a project before generating tests.

Generate Tests can be run for a single method or an entire class. This process will build and probe the target assembly. The Z3 Solver leverages symbolic execution to recommend testing parameters. Subsequently test code is emitted and profiled to capture and retain all test cases that increase coverage of the target code. The test set is continually deduped to retain parameters that maximize coverage and minimize repetition. The IntelliTest results window displays probing status and the list of tests created with inputs, outputs, and assertion results. These tests can be saved to the created projects or to new projects as desired. Saving test provides the choice of an existing project or creating a new project into which the tests are saved.

Try out the IntelliTest Support for .NET 6+ and NetStandard by enabling it in Tools > Manage Preview Features > “ IntelliTest support for NetFx and Net6 using Z3 v4 (restart required)”.

Publish Blazor WebAssembly to Azure Static Web Apps

In this release we have added the ability to publish ASP.NET Core Blazor WebAssembly (WASM) projects to Azure Static Web Apps. When you publish a Blazor WASM project after you select Azure as the target, you will now see an option to select Azure Static Web Apps. See the image below.

Publish Blazor WebAssembly to Azure Static Web Apps

You may be interested in publishing your Blazor WASM project to Azure Static Web Apps to take advantage of its built-in capabilities as well as a potentially lower cost versus publishing to a compute-based Azure service. Some of the built-in capabilities include global hosting, integration with backends like Azure Functions and much more.


C++ and game development

Unreal Engine Macros Formatting for C++

In response to this Developer Community ticket and community feedback, we have added an option to use special indentation rules for Unreal Engine macros. Available as a preview feature, Visual Studio will detect and use indentation and formatting rules for your Unreal Engine reflection macros.

To turn on Unreal Engine specific formatting, search “Unreal Engine” in Options or go to Tools -> Options -> Text Editor -> C/C++ -> Code Style -> Formatting -> Unreal Engine and check “Apply special formatting for Slate declarative syntax and Unreal Engine reflection macros.”

Once enabled, Visual Studio will properly indent code on lines after reflection macros and use special rules for the Slate declarative syntax.

Unreal Engine Naming Convention Checker for C++

Visual Studio will now give you hints when your symbols are not conformant to the Unreal Engine coding style. After adding an .editorconfig file  to your Unreal Engine project, Visual Studio will display naming convention warnings in the Error List and provide a Quick Fix option upon right-clicking.

While this results from Unreal Engine developer feedback, the feature is not specific to Unreal Engine. You can customize your own .editorconfig file for Visual Studio to follow.

This feature is on-by-default. To change whether Visual Studio should treat the checks as Warnings or Suggestions, go to Tools -> Options -> Text Editor -> C/C++ -> Code Style -> Linter and change “Naming Convention (experimental)”. Ensure that you have .editorconfig file.
