When declaring a Windows Communication Foundation (WCF) OperationContract
method as one-way,
that service method won’t return any result, not even an underlying empty confirmation message. These are fire-and-forget methods that are useful in
event-like communication. Therefore, specifying a return type has no effect and can confuse readers.
Exceptions
The rule doesn’t report if OperationContractAttribute.AsyncPattern
is set to true.
