MarshalByRef problem

[jonx1]

Hope someone can help me on this one. I have an SAO, which includes a method that returns a marshalByRefObject. The server compiles without a hitch. I then run soapsuds against it to get the client interface dll. On the client side I can get the SAO object, no problem and can access methods on it that return regular value types. However when I invoke the method that returns the additional marshalByRefObject I get the exception below.

 

Now I know that if I was returning an object by value I'd have to create a generic.dll containing the value type so both the server and client can see it then run soapsuds with the -gc option but in this case I'm using marshalByRef's only so this shouldn't apply, right?

 

I've also included the code I'm using below.

 

I'd appreciate any tips you can give me on this.

 

-Jon.

If you are getting an InvalidCastException, can you not break in that function and see what exactly the type is that you are getting back?
