Remote Method Service Call

Thanks. This line from the sample should be added to the documentation:

"Using the ServerMethodDelegate means that you must define a class/method stub on the client and use the same assembly name on the server as well as the client."

In other words, the issue was that the Server Project dll name was different than the client assembly dll. (The default project template of course adds "Web" to the end of the Server project dll name.)

I have a number of RMSC that work in DevForce 2010, but I can't seem to get them to work in 2012. I can do a normal query and get entities back, so I don't think it is a EM configuration issue.

I have tried this from a test project, and the error is always the same:

System.IO.FileNotFoundException: Could not load file or assembly 'SilverlightApplication62' or one of its dependencies.

ServerMethods.cs is linked to the SL project for the Delegate.

This is the test Server Method:

public static class ServerMethods
    {
        [AllowRpc]
        public static object GetNumberOfOrders(IPrincipal principal,
          EntityManager entityManager, params Object[] args)
        {
            return 5;
        }
    }

This is the SL call:

public async void GetNumberOfOrderFromServer(int id) {
            var _entityManager = new JetAnalyticsEntities();
            var serverMethod = new ServerMethodDelegate(ServerMethods.GetNumberOfOrders);
            var returnValue = (int)await _entityManager.InvokeServerMethodAsync(serverMethod, id);
        }

I also tried it using strings:

public async void GetNumberOfOrders2(int id)
        {
            try
            {
               string typeName = "SilverlightApplication62.ServerMethods, SilverlightApplication62";
               string methodName = "GetNumberOfOrders";
               var result = (int) await _entityManager.InvokeServerMethodAsync(typeName, methodName, id);
            }
            catch (Exception ex)
            {
              
            }
        }

The error message is always the same about the file could not be found. I am assuming that it can't find ServerMethods.cs, as a breakpoint in the file is never hit. This is the full error message from the log:
