// The MyAppKeyPair.snk linked in the project is not present in the repository,
// you should generate your own strong name key and keep it private.
//
// 1) You can generate a strong name key with the following command in the Visual Studio command prompt:
// sn -k MyKeyPair.snk
//
// 2) The next step is to extract the public key file from the strong name key (which is a key pair):
// sn -p MyKeyPair.snk MyPublicKey.snk
//
// 3) Display the public key token for the public key:
// sn -t MyPublicKey.snk
//
// 4) Go to the project properties Singing tab, and check the "Sign the assembly" checkbox,
// and choose the strong name key you created.
//
// 5) Register and get your trial license from https://www.woutware.com/SoftwareLicenses.
// Enter your strong name key public key token that you got at step 3.
