Could not resolve type with token 01000053 from typeref

[jamescrosswell]

I'm trying to upgrade to the latest version of Verify.Xunit and I've bumped into the following issue only on CI and only when running the tests on mono (no issue running the same tests on Mac OS locally and no issues running them on Windows where the full .NET Framework is available):

System.TypeLoadException : Could not load type of field 'ConvertUtils:TypeCodeMap' (0) due to: Could not resolve type with token 01000053 from typeref (expected class 'System.Collections.Frozen.FrozenDictionary`2' in assembly 'System.Collections.Immutable, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a') assembly:System.Collections.Immutable, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a type:System.Collections.Frozen.FrozenDictionary`2 member:(null)

Since I only get this on CI (not on my M2 Macbook), I'm guessing it's a dependency issue. The error message cites System.Collections.Immutable 8.0.0 which is a dependency of Argon 0.25.0, which in turn is a dependency of Verify.Xunit 28.4.0 (looks like it was introduced in Verify.Xunit 27.0.0).

Any idea what I might be missing on the CI runner or any other potential cause of this error?

can you share your csproj contents?

[jamescrosswell]

Generally we're targeting net9.0;net8.0;netstandard2.1;netstandard2.0;net462 (plus various mobile targets).

The tests that are experiencing problems are targeting net462 (which looks to be OK for System.Collections.Immutable).

They only fail on macos and ubuntu though (so when running on mono).

[SimonCropp]

i assume from this that dropping net462 would not effect sentry #784 (comment)

If by "dropping" you mean bumping to net472 then yeah, I think that's true. We only use Verify in our test assemblies, which target net48.

[SimonCropp]

i am confused. do your test target net462 or net48 ?

[jamescrosswell]

Sorry, I made that confusing.

The assemblies being tested target net462

The tests themselves target net48
