BeAssignableTo does not work across multiple layers of inheritance and multiple assemblies

[tnotheis]

My ArchUnit tests test for assignability across multiple layers of inheritance, like so:

// Assembly 1
public class Parent;

// Assembly 2
public class Child : Parent;

// Assembly 3
public class Grandchild : Child;

// ArchUnit test
public class Tests
{
    private static readonly Architecture Architecture = new ArchLoader()
            .LoadAssemblies(typeof(Parent).Assembly, typeof(Child).Assembly, typeof(Grandchild).Assembly)
            .Build();
    
    [Fact]
    public void Test()
    {
        Classes().That().Are(typeof(Grandchild))
            .Should().BeAssignableTo(typeof(Parent))
            .Check(Architecture);
    }
}

(I created a minimal example, which you can find here: https://github.com/tnotheis/archunit-bug-example)

With version 0.11.0 this worked just fine. But since I upgraded to version 0.11.1, the test fails with the following error:

AssemblyOfGrandchild.Grandchild is not assignable to "AssemblyOfParent.Parent"

It only fails if Child and Grandchild reside in different assemblies. If you move the Grandchild class into AssemblyOfChild the test passes.

Are there any Updates about this Bug?

Hi, this is currently caused by types not being resolved correctly and is fixed by #318. I'll see that I get this PR merged soon.

We've just released #318 as a preview release 0.11.3-preview.1. Would you be able to check whether this resolves this issue for you?

I just tested my cases quickly and it looks like it works so far 😊

@alexanderlinne
After retest, for the given case it works, but with freezing files there is a problem because the EvaluatedObjectIdentifier is not unique,
when working with multiple assemblies with same namespaces.

	new StringIdentifierComparer()
