xunit.v3 Migration

Migrate .NET test projects from xUnit.net v2 to xUnit.net v3. The outcome is a solution where all test projects reference xunit.v3.* packages, compiles cleanly, and all tests pass with the same results as before migration.

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
