Add license key

Now that you’ve built your application, and tested it in a deployment environment, you might be ready to purchase a license. Please contact sales in order to get a license key.

When you do not want to be in the watermarked demo/trial mode, it is important that you initialize Apryse library with a valid license key before using any Apryse classes.

After this.InitializeComponent() of App.xaml.cs in your application, add:

pdftron.PDFNet.Initialize("Insert commercial license key here after purchase");
