still has error... What is the problem..
thanks....

Hi Serkan,
the issue here is you are trying to share a class, not a type.
By deleting the "generated class based on the type specified by the
WebService" you essentially invalidate the proxy you created.
When dealing with WebServices, you (exceptions left alone) generally
share a WSDL file. NOT the assembly with the dataclasses exposed by
the WebService.
The WSDL file is then used on the client for generating "Proxy
classes" for you. These classes are NOT THE SAME classes as the server
exposes, but ARE THE SAME TYPES.
The framework will take care of serializing & deserializing. U can
just deal with "objects" in your code on both Server & Client side.
Hope this helps,
Marvin Smit.

I think I am facing the same problem:
A library defines a type. That type is being returned by a method of a
webservice and being used by a client of that webservice.
My issue appears earlier; at compile time; when I receive a "Class1 is an
ambiguous type" when I try to compile the client app. (Class1 is the type
defined in my library).
Is it something I shouldn't be doing?

Hi,
The "Class1" is ambiguous issue might also come from, using the
"Class1" as declerator while multiple namespaces in scope expose a
"Class1" class.
So, if you have
#using Library1;
#using Library2;
Class1 myClass1 = new Class1();
And both Library1 and Library2 contain a class call "Class1", you'll
get this error.
Hope this helps,
