Skill instructions
MSTest v3 - v4 Migration Migrate a test project from MSTest v3 to MSTest v4. The outcome is a project using MSTest v4 that builds cleanly, passes tests, and accounts for every source-incompatible and behavioral change. MSTest v4 is not binary compatible with MSTest v3 -- any library compiled against v3 must be recompiled against v4. When to Use - Upgrading MSTest.TestFramework, MSTest.TestAdapter, or MSTest metapackage from 3.x to 4.x - Upgrading MSTest.Sdk from 3.x to 4.x - Fixing build errors after updating to MSTest v4 packages - Resolving behavioral changes in test execution after upgrading to MSTest v4 - Updating custom TestMethodAttribute or ConditionBaseAttribute implementations for v4 When Not to Use - The project already uses MSTest v4 and builds cleanly -- migration is done - Upgrading from MSTest v1 or v2 -- use migrate-mstest-v1v2-to-v3 first, then return here - The project does not use MSTest - Migrating between test frameworks (e.g., MSTest to xUnit or NUnit) Inputs | Inp
