Causes a communication object to transition from the created state into the opened state.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The communication object is in a Faulted state and cannot be modified.
The default interval of time that was allotted for the operation was exceeded before the operation was completed.
When a CommunicationObject 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. When called, the Open method causes a CommunicationObject to enter into the Opening state and calls OnOpening, Open, and OnOpened. The OnOpened method completes the Open method by setting the state of the object to the Opened state.
Credentials Capture with Windows Authentication
When using Windows authentication, credentials used by the service are based on the current context thread. The credentials are obtained when the Open method is called.
