IAssemblyFixture is not working if my test project targets .net framework. (using 4.8 in this case)
The exception raised in test runner:
"The following constructor parameters did not have matching fixture data: MyAssemblyFixture fixture"
I can provide a minimal reproducible example if necessary, but this can be easily repro'd in the current commit by changing this line in AssemblyFixture.Tests.csproj to:
<TargetFramework>net48</TargetFramework>
Rebuild the project and none of the tests will run.
