Description
On aggressively-trimmed Apple-mobile Helix legs such as iossimulator-arm64 CoreCLR, reflection-heavy test projects get their dependencies stripped by the trimmer, so the host discovers zero test cases and XHarness reports the run as a crash with Tests run: 0 and APP_CRASH. To keep these legs green we keep adding projects to ProjectExclusions in src/libraries/tests.proj, for example Microsoft.Extensions.DependencyInjection.Tests and Microsoft.Extensions.DependencyInjection.ExternalContainers.Tests, each trading CI stability for lost coverage.
Run the Apple-mobile library-test Helix legs without aggressive trimming, as was previously done on rolling builds, so reflection-heavy projects keep the metadata they need, we regain coverage over currently-excluded areas, and the legs become more stable. Once coverage is restored, re-enable the projects excluded purely due to trimming.
