Some test text!
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 PDFTron library with a valid license key before using any PDFTron classes.
App.xaml.cs in your application, add:
pdftron.PDFNet.Initialize("Insert commercial license key here after purchase");
