What the check File.WriteAllBytes("testasm.dll", data) in tests?

Hello!

I am thinking to add github actions and, accordingly, restore tests. I have updated the nuget packages and upgraded to netcoreapp 3.1. But the chair ran into the fact that my tests fall in this place https://github.com/kekekeks/XamlX/blob/697a419675a8055b7ef9a1904360359522b30616/tests/CecilTests/CompilerTestBase.cs#L60

With the following error

  Message: 
    System.IO.IOException : The process cannot access the file '.\XamlX\tests\CecilNetstandardTests\bin\Debug\netcoreapp3.1\testasm.dll' because it is being used by another process.
  Stack Trace:

    FileStream.ctor(String path, FileMode mode, FileAccess access, FileShare share)

If I comment out, most of the tests pass (I don’t think those test pairs are related to this). What this check?

P.S. If necessary, you can try, for example, using System.IO.Abstractions.TestingHelpers, writing something like this

What happens if you change the file extension from dll to bin?

Ok, I added an extra condition on build for this in #31
