Use this skill before answering, planning, or editing whenever .NET tests or CI are switching from VSTest to Microsoft.Testing.Platform (MTP), or an MTP migration behaves differently. Triggers include "switch from VSTest"; MSTest/NUnit/xUnit MTP enablement; OutputType=Exe only for test projects in Directory.Build.props; EnableMSTestRunner, EnableNUnitRunner, UseMicrosoftTestingPlatformRunner, or YTest.MTP.XUnit2; .NET 10 global.json test.runner and TestingPlatformDotnetTestSupport; translating…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# VSTest -> Microsoft.Testing.Platform Migration

Migrate a .NET test solution from VSTest to Microsoft.Testing.Platform (MTP). The outcome is a solution where all test projects run on MTP, `dotnet test` works correctly, and CI/CD pipelines are updated.

## First Action

Inspect the supplied project, `Directory.Build.props`, `global.json`, and CI
files before searching the web or answering from memory. Resolve the framework
and SDK mode first: .NET 9 and earlier use the compatibility property plus the
`--` separator; .NET 10 native MTP uses `global.json`, removes that property,
and passes MTP arguments without the separator. For central properties, never
condition on `IsTestProject` in `Directory.Build.props`; use a property already
available there, such as `MSBuildProjectName`.

> **Important**: Do not mix VSTest-based and MTP-based .NET test projects in the same solution or run configuration -- this is an unsupported scenario.

## When to Use

- Switching from VSTest to Microsoft.Testing.Platform for any supported test framework
- Enabling `dotnet run` / `dotnet watch` / direct executable execution for test projects
- Enabling Native AOT or trimmed test execution

How to install

The exact contents, by fingerprint
mdr add dotnet/skills/migrate-vstest-to-mtp@sha256:e4984767f47f06b9

The line at the top of this page pins the label git:20260902.3b670a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
