|A socket Connect operation.|
|A socket Disconnect operation.|
|A socket Receive operation.|

|A socket ReceiveMessageFrom operation.|
|A socket Send operation.|
|A socket SendPackets operation.|

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 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.
The type is used by the SocketAsyncEventArgs::LastOperation property.
