You can do the same thing using the AWS SDK for .NET by doing something similar to:
Bear in mind that when you image an instance using the --no-reboot option, it is imaged without cleanly shutting down the image. The next time you start your server based on this image, the Shutdown Event Tracker will pop up wondering why you lost power.
