mtp-hot-reload

separate

Set up or recover MTP hot reload for a long-lived console-host edit/re-run loop in a Microsoft Testing Platform project. Use for explicit MTP console requests such as "enable hot reload", "dotnet run to rerun on edit", or unsupported/rude edits. Covers setup, run/watch, restarts, filters, and the VSTest no-mutation fallback. For one-time runs, exact commands, filter errors, TRX/dumps, or merely a failing test, use run-tests. Do not use when Test Explorer or an IDE should rerun tests without an MTP console host. Excludes editor integration, CI, and writing/debugging tests.

When to use

• User explicitly asks for test hot reload
• User wants a host to stay running and automatically rerun after repeated edits
• User needs to set up MTP hot reload in their project

When not to use

• User needs to write new tests from scratch (use general coding assistance)
• User needs to diagnose why a test is failing (use diagnostic skills)
• User asks about Visual Studio or VS Code Test Explorer hot reload or an IDE-integrated rerun experience (different feature, not MTP console-host hot reload)
• User asks whether the editor can auto-rerun affected tests after source edits without using an MTP console host
• User wants one normal run without rebuilding (use `run-tests`)
• User needs CI/CD pipeline configuration
