The Upgrade Wizard for WPF cannot upgrade projects targeting 4.8 .NET framework

The Upgrade Wizard for WPF cannot upgrade projects targeting the 4.8 .NET Framework.

1. Install the latest extension for WPF 
2. Create a new project targeting the 4.8 .NET Framework
3. Try to launch the Upgrade Wizard from the Telerik menu 
4. See the error - The project cannot be upgraded because the target framework does not match

Hello, 

I’m happy to let you know that the reported issue has been fixed.

A new version of the extension has been released and is now available on the Visual Studio Marketplace. You can install the latest version and proceed with testing at your convenience. 

Regards,
