Thanks Dino.
I found out the problem is with one of my class. But I still dont understand
why it was breaking. I have a class say A. Class B is inherting from A.
Class C inherits from B(A->B->C). In class C I shadowed one of the property
to make it read only. For some reason , when I call the webservice it
breaks. When I directly calls my asmx, it works fine. But when I call the
webservice thru proxy, it just gave me the same error. I dont know why I
shouldnt declare a read only property which overrides by parent class. Any
idea?
Thanks
