.NET Application License Protection

Add License Protection to your .NET application whether it is a .NET WinForms application, a .NET WPF application, an Office add-on, a web service, a Sharepoint app, etc..

With QLM’s .NET Licensing Framework, you can provide permanent, trial or subscription based licensing to your customers. Your customers can easily activate their license online when connected to the internet or offline if they are not connected to the internet.

Here are some of the features supported by QLM’s .NET Licensing System:

• Bind a license key to a specific computer
• Create time limited trial license keys
• Online and Offline activation of license keys
• eCommerce integration with leading eCommerce providers
• Fully automated workflow for Subscription based products
• Add a Check for Updates feature to your software so that your customers are always current with your latest release
• Send scheduled customized email messages to your customers to notify them of specials and/or upcoming releases.
• Track installs and uninstalls of your software to assist you in understanding customer behavior and improve download trends

The QLM API is available as a .NET assembly that you reference in your project.

For WinForms and WPF, QLM includes .NET User Controls for license activation that you simply drop into your form. These User Controls provide a user interface that allows the user to enter a license key and activate it. This eliminates most of the coding required to integrate QLM into your application.

To help you get started, we provide many .NET samples that you can use as a reference to implement licensing in your own .NET application. The samples are located in the following folders:
