Adoption guide

Repositories that prefer first-party tooling and existing MSTest conventions.

Unit Testing guide

Why it appears in the guide: Microsoft's test framework, especially practical in Visual Studio-centred solutions. Trade-off: Compare its current data-driven and extensibility needs against the alternatives before a large migration.

Compatibility metadata lists 5 target frameworks; confirm the exact target used by your application.

How to read this guidance

Sources: published NuGet v3 registry metadata and explicit NuBrowse editorial guides. Refresh: package metadata is refreshed from NuGet when the page loads. Limit: this is not a security, legal or compatibility guarantee; validate the selected version in your project.
