[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Provides support for implementing the event-based asynchronous pattern.
For more information about

'Declaration Protected Sub InvokeAsync ( _ beginOperationDelegate As ClientBase<(Of <(<'TChannel>)>)>..::..BeginOperationDelegate, _ inValues As Object(), _ endOperationDelegate As ClientBase<(Of <(<'TChannel>)>)>..::..EndOperationDelegate, _ operationCompletedCallback As SendOrPostCallback, _ userState As Object _ )
Parameters
- beginOperationDelegate
- Type: System.ServiceModel.ClientBase(Of TChannel).BeginOperationDelegate
A delegate that is used for calling the asynchronous operation.
- inValues
- Type:
System.Object
()
The input values to the asynchronous call.
- endOperationDelegate
- Type: System.ServiceModel.ClientBase(Of TChannel).EndOperationDelegate
A delegate that is used to end the asynchronous call after it has completed.
- operationCompletedCallback
- Type: System.Threading.SendOrPostCallback
A client-supplied callback that is invoked when the asynchronous method is complete. The callback is passed to the ClientBase(Of TChannel).BeginOperationDelegate.
- userState
- Type: System.Object
