Remarks

The method called must be marked with the AllowRpcAttribute and correspond to the ServerMethodDelegate signature. InvokeServerMethodAsync enables a client-side caller to invoke an arbitrary static method on the server using an asynchronous call. The server method is called once only. An outstanding request can be cancelled using the System.Threading.CancellationToken. This feature is only available in certain editions of DevForce.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
