Project Migration to .NET 4.6.2 and .NET 6
With the 2024 Q2 release (from May 2024), the Telerik UI for WPF product no longer provides support for .NET Framework 4.0 and 4.5, and also .NET Core 3.1. The minimum supported .NET Framework version is now 4.6.2 and for .NET is 6.
This article describes how to migrate to a newer version of .NET.
Migrating from .NET Framework 4.0/4.5 to .NET Framework 4.6.2
There is no difference in the APIs between the different types of Telerik dlls, so you need to only change the Target framework of the project and the referenced Telerik dlls.
Download and install the corresponding .NET Framework developer pack (4.6.2 or later).
-
Right click on the WPF project in Visual Studio and select the Properties option from the context menu.
-
In the Target framework menu, select .NET Framework 4.6.2 or later version and save the project file.
Update the referenced Telerik assemblies using the preferred installation approach. For example, via NuGet or the .msi installer.
You may need to manually delete the bin and obj folders before rebuilding the project in order to ensure that any Visual Studio assemblies cache is cleared.

Migrating from .NET Framework 4.0/4.5 to .NET 6
To migrate from .NET Framework to .NET, you can create a new .NET 6 (or later) project and include the corresponding files from the .NET Framework project. Then, install the Telerik .NET assemblies in the new project. This approach is described in more detail in the Migrating to .NET article.
