Re: Passing User Define class to web service.

Joel,

First, you should try to update your web reference, then go to the generated
proxy and verify that the method exists, this is what you most likely found
regarding being up to date. Remember, that when the new web service proxy is
generated it will overwrite any modifications you have made to the current
proxy so make sure you have a backup of your modifications.

Second, if this is unsuccessful, then delete all temporary ASP.net files. I
have encountered errors and know of others encountering errors as a result of
using cached files. Others may be able to explain this in more details since
this approach is primitive, but I and others have found that it works.


Let me know how this goes.
