ClientBase<TChannel>.ChannelBase<T>.ICommunicationObject.BeginOpen Method (AsyncCallback, Object)
Begins an asynchronous operation to open a communication object.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
- Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous open operation.
Return ValueType: System.IAsyncResult
The IAsyncResult that references the asynchronous open operation.
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 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.
