Any command that is running on the PIXL can be aborted by calling the Abort method on the PIXLClient.

pixl.Abort();

This will notify the PIXL that the command it is currently running should come to a premature end in a controlled manner. Aborting a command might not cause the command to end immediately.

var result = pixl.Abort().Result;

if (result.IsSuccess)
    Console.WriteLine("Abort has been processed.");
else
    Console.WriteLine($"Operation could not be aborted because {result.Message}");

If the progress of a pending Abort is required, please check the OperationalStatus property of the PIXLClient. In particular, the CommandStatus property provides the status of the running command.
