[TestClass]
// The VSTest_* tests below invoke `dotnet test` against the same shared VSTest project
// path for every target framework. Running them in parallel races on MSBuild outputs
// such as `bin/Release/<tfm>/TelemetryVSTestProject.runtimeconfig.json` and shared
// `obj/` files, which causes intermittent `GenerateRuntimeConfigurationFiles` failures.
// Serialize all tests in this class to keep the suite deterministic.
