platform-detection
Reference data for detecting the test platform (VSTest vs Microsoft.Testing.Platform) and test framework (MSTest, xUnit, NUnit, TUnit) from project files. DO NOT USE directly — loaded by run-tests, mtp-hot-reload, and migrate-vstest-to-mtp when they need detection logic.
npx skills add dotnet/skills --skill platform-detection --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Test Platform and Framework Detection Determine **which test platform** (VSTest or Microsoft.Testing.Platform) and **which test framework** (MSTest, xUnit, NUnit, TUnit) a project uses. **Detection files to always check** (in order): `global.json` → `.csproj` → `Directory.Build.props` → `Directory.Packages.props` ## Detecting the test framework Read the `.csproj` file **and** `Directory.Build.props` / `Directory.Packages.props` (for centrally managed dependencies) and look for: | Package or SDK reference | Framework | |--------------------------|-----------| | `MSTest` (metapackage, recommended) or `<Sdk Name="MSTest.Sdk">` | MSTest | | `MSTest.TestFramework` + `MSTest.TestAdapter` | MSTest (also valid for v3/v4) | | `xunit`, `xunit.v3`, `xunit.v3.mtp-v1`, `xunit.v3.mtp-v2`, `xunit.v3.core.mtp-v1`, `xunit.v3.core.mtp-v2` | xUnit | | `NUnit` + `NUnit3TestAdapter` | NUnit | | `TUnit` | TUnit (MTP only) | ## Detecting the test platform The detection logic depends on the .NET SDK version. Run `dotnet --version` to determine it. ### .NET SDK 10+ On .NET 10+, the `global.json` `test.runner` setting is the **authoritative source**: - If `global.json` contains `"test": { "runner": "Micro

What does the platform-detection skill do?
Reference data for detecting the test platform (VSTest vs Microsoft.Testing.Platform) and test framework (MSTest, xUnit, NUnit, TUnit) from project files. DO NOT USE directly — loaded by run-tests, mtp-hot-reload, and migrate-vstest-to-mtp when they need detection logic.
How do I install it?
Run `npx skills add dotnet/skills --skill platform-detection --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From dotnet/skills, a repository with 4,927 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
