Visual Studio adapter 3.1.0 2025 May 3

Today, we're shipping two new releases:

• xUnit.net Core Framework v3 2.0.2 (release notes)
• xUnit.net Visual Studio adapter 3.1.0

It's been 3 months since the release of 3.0.2.

As always, we'd like to thank all the users who contributed to the success of xUnit.net through usage, feedback, and code. 🎉

Important

This version is updated to use the a 2.x version of xunit.v3.runner.utility, which has a new minimum target version of .NET 8. This means that running test projects that target .NET 6/7 is no longer supported (and may not work). If you're stuck on one of these out-of-date versions of .NET, you may need to stick with the 3.0.2 release.

Release Notes

These release notes are a comprehensive list of changes from 3.0.2 to 3.1.0.
