The IVsWCFAsyncResult type exposes the following members.
Methods

Cancel | Cancels an asynchronous method call. |
|
GetCustomState | Returns custom state object passed to an asynchronous method |
|
GetMethodResult | Returns the HResult returned by the method that was called asynchronously. |
|
IsCancelled | Returns a value determining whether an asynchronous method was canceled. |
|
IsCompleted | Returns a value determining whether an asynchronous method was completed. |

Remarks
Some object methods are exposed in two versions: synchronous and asynchronous. The asynchronous version follows the .NET asynchronous call pattern. An important distinction is that the asynchronous version does not support passive waiting. The consumer of these methods can be notified about method completion either through the IVsWCFCompletionCallback callback mechanism, or by polling the IVsWCFAsyncResult.
