Causes a communication object to transition from the created state into the opened state.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
When an ICommunicationObject is instantiated, it begins in the Created state. In the Created state, the object can be configured (for example, properties can be set, or events can be registered), but it is not yet usable to send or receive messages. The Open method causes an ICommunicationObject to enter into the Opening state, where it remains until the open operation succeeds, the open operation times out or fails and the object becomes faulted, or the ICommunicationObject is aborted.
There is also an asynchronous version of the open method that is initiated by calling and completed by calling EndOpen(IAsyncResult).
