Telerik Document Processing Libraries and WinForms .NET application

Updated on Aug 4, 2026

Since the Telerik Document Processing Libraries depend on some types from WPF using any library in a WinForms application requires making changes in the project file. This is not necessary in the .NET framework projects where you can just add the references in Visual Studio.

By default, when creating a WinForms .NET application the Microsoft.WindowsDesktop.App.WindowsForms framework is added. This does not include the required WPF references.

WinForms .NET project file before adding WPF support for Telerik Document Processing Libraries

To add the required references, you need to:

1. Edit the project file:

Visual Studio project file opened for editing to configure Telerik Document Processing Libraries

2. Under the UseWindowsForms line, add the UseWPF tag. The file should look like this:

WinForms .NET project file with the UseWPF tag added under UseWindowsForms

3. Save and reload the file. Now, you should see the Microsoft.WindowsDesktop.App in the frameworks node:

This is all that is required and now you can continue with your application.
