AppDomain.TypeResolve not called for dynamic type

Demorepo:

https://github.com/gabbersepp/csharp-dynamic-replace-class

How to use:

1. Checkout
2. Compile
3. Delete TestLib.dll & TestLib.pdb from console/bin/Debug
4. Execute console.exe through cmd

Old SO post:

Replace existing class definition at runtime with newly created type

Given:

A class in a lib:

namespace Test.TestLib
{
    public class Class1
    {
    }
}

And a second class which creates an instance of it:

namespace console
{
    public class AnotherClass
    {
        public void Create()
        {
            new Class1();
        }
    }
}

And a console app that calls create:

    static void Main(string[] args)
    {
        //...
        new AnotherClass().Create();
    }

Please keep in mind that only Class1 is in an extra lib. The other two classes are in the same.

What I want to do:

Replace the Assembly at runtime:

        AssemblyName dynamicAssemblyName = new AssemblyName("TestLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null");
        dynamicAssembly =
            AssemblyBuilder.DefineDynamicAssembly(dynamicAssemblyName, AssemblyBuilderAccess.Run);
        var dynamicModule = dynamicAssembly.DefineDynamicModule("TestLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null");

But I want not provide the type at this time. Instead I use:

AppDomain.CurrentDomain.TypeResolve += CurrentDomain_TypeResolve;

    private static Assembly CurrentDomain_TypeResolve(object sender, ResolveEventArgs args)
    {
        Console.WriteLine("resolve type");
        if (args.Name.Contains("TestLib"))
        {
            dynamicModule.DefineType("Test.TestLib.Class1", TypeAttributes.Class | TypeAttributes.Public).CreateType();
            return dynamicAssembly;
        }

        return null;
    }

Problem:

The event is not called when the line new AnotherClass().Create(); is executed. Instead an exception is thrown:

System.TypeLoadException: Der Typ "Test.TestLib.Class1" in der Assembly "TestLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" konnte nicht geladen werden

something like:

System.TypeLoadException: The type "Test.TestLib.Class1" in the assembly "TestLib, Version = 1.0.0.0, Culture = neutral, PublicKeyToken = null" could not be loaded
