Display progress information
public void WriteProgress (System.Management.Automation.ProgressRecord progressRecord);
The pipeline has already been terminated, or was terminated during the execution of this method. The Cmdlet should generally just allow PipelineStoppedException to percolate up to the caller of ProcessRecord etc.
Not permitted at this time or from this thread. WriteProgress may only be called during a call to this Cmdlet's implementation of ProcessRecord, BeginProcessing or EndProcessing, and only from that thread.
Use WriteProgress to display progress information about the activity of your Cmdlet, when the operation of your Cmdlet could potentially take a long time.
By default, progress output will be displayed, although this can be configured with the ProgressPreference shell variable.
