migrate-xunit-to-xunit-v3

separate

Migrate .NET test projects from xUnit.net v2 to xunit.v3 and fix v3 breaks. Use for package/CPM conversion, OutputType=Exe, preserving the VSTest or MTP runner (including projects currently using YTest.MTP.XUnit2), incompatible TFMs, async void tests, string-to-Type attributes, custom Fact/Theory/BeforeAfterTest attributes, Xunit.SkippableFact, xunit.abstractions/extensibility consolidation, and Xunit.Combinatorial/StaFact compatibility. Do not use for framework conversion or a runner-only migration. For xUnit v3 MTP filter syntax, also use migrate-vstest-to-mtp.

When to use

• Upgrading test projects from `xunit` (v2) packages to `xunit.v3`
• Resolving compilation errors after updating xunit package references to v3

When not to use

• Migrating between test frameworks (e.g., MSTest or NUnit to xUnit.net) — different effort entirely
• Migrating from VSTest to Microsoft.Testing.Platform — use `migrate-vstest-to-mtp`
• The projects already reference `xunit.v3` — migration is done
