The overload is also available in the online docs: http://www.ranorex.com/Documentation/Net/InvokeRemotely(Control..::.RemotelyInvokedDelegate) Invokes the delegate deleg remotely at the Control associated with this instance.
InvokeRemotely(Control..::.RemotelyInvokedDelegateWithInputData, Object) Invokes the delegate deleg remotely at the Control associated with this instance.
The latter method does not exist though. Only the "public object InvokeRemotely(Control.RemotelyInvokedDelegate deleg);" is in the metadata.
