Microsoft has released its February 2026 update for Visual Studio, delivering a fresh set of improvements across AI assistance, diagnostics, and core developer workflows in the IDE. The latest Visual Studio update continues the platform’s evolution with smarter tools and performance refinements aimed at helping developers stay productive in real-world development scenarios.
Here’s a quick rundown of the newest features designed to make you faster, sharper, and more efficient as a developer:
Smarter Test Generation with GitHub Copilot
Generate unit tests for your C# code faster using Copilot. Just type @test in Copilot Chat, describe what you want to validate, and it creates the test code for you — with support for xUnit, NUnit, and MSTest.
Slash Commands for Custom Prompts
Access your favorite custom prompts faster using slash commands in Copilot Chat. Type / and your saved prompts appear at the top of the list, marked with a bookmark icon for easy access.
C++ App Modernization (Public Preview)
Copilot-powered modernization for C++ is now available in Public Preview. Upgrade your C++ projects to the latest MSVC versions and resolve upgrade-related issues with guided assistance from Copilot.
DataTips in IEnumerable Visualizer
Debugging just got easier. You can now use DataTips inside the IEnumerable Visualizer. Hover over any value in the grid to see the full underlying object — the same DataTip experience you’re used to in the editor or Watch window.
Analyze Call Stack with Copilot
When debugging pauses, select Analyze with Copilot in the Call Stack window. Copilot reviews the current stack and explains why execution stopped — whether your thread is waiting, looping, or blocked.
Profiler Agent with Unit Test Support
The @profiler agent now works with unit tests. Use your existing tests to measure performance improvements and optimize code more effectively. It can automatically discover relevant unit tests or BenchmarkDotNet benchmarks that exercise performance-critical paths.
