Returns a value that indicates whether a message has arrived within a specified interval of time.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Calling does not result in a message being received or processed in any other way.
The method exists primarily for transacted scenarios where the user wants to receive the message using a transaction. When using just Receive normally for this, the user must create the transaction and then call Receive and hope the message arrives before the transaction times out, which may not be possible.
Instead, the user can call with whatever time out they want (even infinite), then when a message arrives they can open the transaction, call Receive and be confident that they can get the message back before the transaction expires.
This method is synchronous, so it blocks the current thread until a message is available or the time out occurs. Use when it is acceptable for the current thread to be blocked while it waits for a message to arrive in the queue. The thread is blocked up to the specified timeout. If you want the application processing to continue without waiting, use the asynchronous BeginWaitForMessage(TimeSpan, AsyncCallback, Object) method.Notes to Implementers
The operation returns false if the specified timeout is exceeded, not a timeout exception.
