Use when identifying a .NET test framework, VSTest versus MTP or conflicting runner configuration. Not for executing or filtering tests, command errors, dumps or migration; use run-tests for execution.
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.

Follow with one concise evidence sentence naming the repository facts needed to justify every requested classification. When `Framework` is requested, name the package or project SDK that identifies it. Use a second sentence only for a conflict, an …

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.
