This type describes the asynchronous socket operation that was most recently completed using a System.Net.Sockets.SocketAsyncEventArgs object. The value of the SocketAsyncEventArgs.LastOperation property is set to SocketAsyncOperation.None until the System.Net.Sockets.SocketAsyncEventArgs instance is used to begin an asynchronous socket operation. The property will then be set to the type of asynchronous operation being performed. This type more easily facilitates using a single completion callback delegate for multiple kinds of asynchronous socket operations. This type is intended for use in the SocketAsyncCallback completion routine.
