InvokeServerMethodAsync

DevForce requires that RPC methods have a specific signature, so your SendMail method would need to look like this:

[AllowRpc]
public static bool SendMail(IPrincipal principal, EntityManager em, params object[] args)

You can then get the EmailMessage from the args:
var emailMessage = args[0] as EmailMessage;

One other thing to watch out for: the EmailMessage must be a "known" type.

Hello,

I am using cocktail 1 with Silverlight and i want to send an email from the application. I found the InvokeServerMethodAsync but i'm not sure how to use this. The examples are not clear for me. I want to do something like:

      EntityManager mgr = new AccoBookingEntities();

      // Make async call
      mgr.InvokeServerMethodAsync(new ServerMethodDelegate(EmailMessage.SendMail), InvokeServerMethodAsyncCompleted,_emailMessage);

the server call is:

    [AllowRpc]
    public static bool SendMail(EmailMessage emailMessage)

Is there a cocktail wrapper for this with something like an operationresult an how to use this....

Thx in advance
