As far as I understood, you are trying to add additional methods to the DomainService class and in order to do this you create another file where you continue the definition of the partial class. I have created a very simple application where I added several methods to the partial class in a separate file and then invoked these methods in the Silverlight client. The methods on the client side are asynchronous and need some special handling. Can you look at the example and tell me in what ways it differs from the scenario you are facing? The example is built against the NorthwindOA database that is installed with OpenAccess.
Thank you for your patience. I am looking forward to hearing from you. In the meantime, you can benefit from browsing our updated online help and the Silverlight related topics.
