If you have two assemblies with the same name but different extensions,
delegate serialization code fails to resolve the proper target assembly and
type.

How to reproduce:

bug.cs:
using System;

class Program
{

    static void OtherDomain () {
        Console.WriteLine ("here {0}", AppDomain.CurrentDomain);
    }

    static void Main(string[] args)
    {
        AppDomainSetup setup = new AppDomainSetup ();
        setup.ApplicationBase = ".";

        AppDomain newDomain = AppDomain.CreateDomain ("NewDomain", null,
setup);
        newDomain.DoCallBack (Program.OtherDomain);
    }
}


Compile this into bug.exe, the create a bug.dll without the Program type.

At runtime this will throw:
Unhandled Exception: System.Reflection.TargetInvocationException: Exception has
been thrown by the target of an invocation.

Server stack trace: 
  at System.Reflection.MonoCMethod.Invoke (System.Object obj, BindingFlags
invokeAttr, System.Reflection.Binder binder, System.Object[] parameters,
System.Globalization.CultureInfo culture) [0x00000] 
...
Exception rethrown at [0]: 
 ---> System.ArgumentNullException: Argument cannot be null.
Parameter name: target
  at System.Delegate.CreateDelegate (System.Type type, System.Type target,
System.String method, Boolean ignoreCase, Boolean throwOnBindFailure) [0x00000] 
  at System.Delegate.CreateDelegate (System.Type type, System.Type target,
System.String method) [0x00000] 


This works under MS as expected.
