External libraries might be a subject of tampering by hackers to work around the licensing infrastructure. It's a good practice to validate its origin by comparing the code signature and making sure it hasn't tampered before executing any functions.
var assembly = Assembly.GetAssembly(typeof(ItemLicense));
var certificate = X509Certificate.CreateFromSignedFile(assembly.Location);
if (certificate.GetCertHashString() != "07FF85A977EF497368AA1ADEB64D43B2B55BD4D8")
throw new Exception("Could not validate 'PoshTrader.Licensing' assembly origin.");
Those attributes serve as important data during communication with our licensing server. Make sure that these attributes are correct, and the version is up to date.

At the beginning of your app life cycle, you need to create an item license object where you pass your main class object with item attributes as a parameter.
var license = new ItemLicense(this);
The next thing you need to do is to check the license status. If the license is not valid, then a window will pop out asking for License Activation. If the user fails to validate his purchase, you will want to terminate the app or take some other action.
