Weird, we did run the ILTrim tests on that PR and the results were only 5 days old:

2026-04-09T23:08:38.7818259Z Running tests: /__w/1/s/artifacts/bin/ILTrim.Tests/x64/Checked/ILTrim.Tests.dll [net11.0|x64]
2026-04-09T23:10:17.8033735Z Tests succeeded: /__w/1/s/artifacts/bin/ILTrim.Tests/x64/Checked/ILTrim.Tests.dll [net11.0|x64]

Oh, wait, where is the list of failing tests coming from?

That one looks expected.

The CI was failing because we also check the tests in ExpectedFailures are actually failing and they were not. Updated it to just the one test, we'll see.

Ah, thanks - my original list was failing locally due to missing ilasm, but that was unrelated to the ci failure.
