This method delegates to SimpleDataPortal but wraps that call within a TransactionScope to provide transactional support via System.Transactions.

Parameters

objectType	A Type object indicating the type of business object to be created.
criteria	A custom criteria object providing any extra information that may be required to properly create the object.
context	Context data from the client.
isSync	True if the client-side proxy should synchronously invoke the server.

async Task< DataPortalResult > Csla.Server.TransactionalDataPortal.Delete	(	Type	objectType,
		object	criteria,
		DataPortalContext	context,
		bool	isSync
	)
