xunit, We just shipped v2 Core Framework 2.6.6 and Analyzers 1.10.0. The core framework update adds assembly-level BeforeAfterTest support, as well as eliminating false security warnings related to old packages from .NET Standard 1.x. We've also added two new analyzers and fixed issues in a few more.
Enjoy!
