PublishAot warning with TUnit 0.21.13

[AArnott]

This isn't the same as #2410, as the warning is different:

Nerdbank.MessagePack.TUnit succeeded with 1 warning(s) (130.6s) → bin\Nerdbank.MessagePack.TUnit\Debug\net9.0\win-x64\publish
C:\Users\andarno.nuget\packages\tunit.core\0.21.13\lib\net9.0\TUnit.Core.dll : warning IL2104: Assembly 'TUnit.Core' produced trim warnings. For more information see https://aka.ms/il2104

This still repros with TUnit 0.25.6.

[AArnott]

Still repros with 0.61.39. In fact there are even more warnings now.

I'm confused at how this is happening at all, given TUnit's major value prop is NativeAOT readiness.

I can still reproduce this in 0.61.58

Can you chuck me some code that's producing it

[PhilippNaused]

@thomhurst The code in the repro steps of this issue and my #2410 both cause compiler warnings.
