Another in my recent series on getting Silverlight 2.0 beta 2 working.
If you create a WCF web service for Silverlight, it’s well known that on the server side you have to change the binding to basicHttpBinding (or use the new Silverlight-enabled WCF service). Then you can use the Add Reference wizard in your Silverlight application and code against the generated ServiceClient.
This works in C#, but in VB you may hit this error at runtime:
The error is “Could not find endpoint element” etc, and it refers to your “client configuration section”.
I fixed this by comparing the ServiceReferences.ClientConfig file generated in a VB project with that for a C# project. Check the Contract attribute of the endpoint element. It should be qualified with the full namespace, by default the name of your app. In this example, it would be:
However, the VB wizard omits the first part of the namespace; then at runtime, it can’t find the service.
Evidence, perhaps, that C# is the language of choice in Microsoft’s developer division.
