I am building a Silverlight app. As I have classes to be consumed by Silverlight and .NET modules, I have created a Silverlight project with all the classes in it and then, a .NET project linking('Add Link') to the classes in Silverlight project. This way, I have one class file compiled separately as Silverlight and .NET assemblies. I want to replicate the same for web service references. Meaning, I have web references in the Silverlight project. I am trying to 'Add Link' to reference.cs from Silverlight project into the .NET project. When I compile the .NET project, the ChannelBase class doesn't get resolved it seems due to disparity in definition of the class in Silverlight and .NET framework libraries. This results in compilation error stating unresolved ChannelBase. Sounds like a dead end to me. Do you see a way around this problem?
