Completes the asynchronous operation started in BeginGetWorkingDirectory.
The working directory on the server.
Before calling BeginGetWorkingDirectory, you need to create a callback method that implements the AsyncCallback delegate. This callback method executes in a separate thread and is called by the system after BeginGetWorkingDirectory returns. The callback method must accept the IAsyncResult returned by the BeginGetWorkingDirectory method as a parameter. This parameter may then be passed to the EndGetWorkingDirectory method to complete the operation.
