[ci-scan] Test failure: CryptoStreamTests.ReadWrite_Success MemberData not found on maccatalyst

[github-actions]

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1429323
Build error leg or test failing: maccatalyst-arm64 Release AllSubsets_CoreCLR - System.Security.Cryptography.Tests

Error Details

CryptoStreamTests.ReadWrite_Success fails on maccatalyst-arm64 (AllSubsets_CoreCLR) because xUnit cannot locate the [MemberData] property ReadWrite_Success_MemberData. This is a known pattern on mobile CoreCLR where xUnit MemberData lookup fails for inherited static members due to aggressive trimming or reflection metadata differences.
