Hi friends, my problem is as follows: When I use my web service, it displays the following error in Silverlight:

"System.Collections.Generic.KeyNotFoundException was unhandled by user code Message="The given key was not present in the dictionary."

I'm new to c # and Silverlight, and don't really know what to do. I can not find a solution on Google.

Thank you very much in advance.

Friends found the problem was not using the namespace "System.ServiceModel" link where I explained some of this here link text
