RE: Do not include the whole key in your code. Use sn -p to extract the public part to a file. Use that in your code you distribute to verify the license.

Using the code from the MSDN articles, I created a small app (LicMaker) to facilitate this. The app is signed with the full key pair. The input is an unsigned .XML license file.
