           Summary: Can't deserialize a dynamic type
           Product: Mono: Runtime
           Version: unspecified
          Platform: Other
        OS/Version: openSUSE 10.2

My code is working in .Net but not in Mono. 
I have a dynamic assembly with dynamic types, created through Reflection.Emit.
During the deserializaton, the BinaryFormatter does not find the dynamic type
because it does not find the dynamic assembly. It happens in .Net but I sort it
out by subscribing the AppDomain.CurrentDomain.AssemblyResolve event and
returning the assembly in the handler. 
The event handler is called also on mono at some stage but I guess there is a
later stage in which is should be called again and it is not. 
The exception trace I get is this:

1) bindableObjectsTests.BindableObjectsMain.ChangeBindable :
System.Reflection.TargetInvocationException : Exception has been thrown by the
target of an invo
  ----> System.TypeLoadException : Could not load type

I've taken a look at the Mono code and I loose the track in an internal call 
invocation (MonoCMethod.Invoke).
