.NET Support Overview
Telerik UI for WPF comes with support for .NET 8 and later.
Telerik provides sets of DLLs built against the different .NET versions which you can reference in an application and start using the Telerik controls.
See how to migrate your app in the Migrating to .NET Core article.
The installation approaches for the .NET versions of the Telerik dlls are the same as the ones for the .NET Framework version. Read more in the Getting Started section of the documentation. The additional setting for .NET 8 and later is that several controls rely on third party NuGet packages. These are automatically installed when adding the Telerik assemblies via NuGet or the Telerik Visual Studio Extension. In case you reference the assemblies manually, one or more of the following packages should be installed manually: System.Data.OleDb, System.Drawing.Common and System.ServiceModel.Http.
.NET 8 Requirements
To work with the Telerik .NET 8 DLLs you will need to have the following installed.
The latest .NET 8 SDK.
Visual Studio 2022 (v17.2 latest preview or newer).
Design-Time Support and Visual Studio ToolBox
The Telerik controls can be drag/dropped from the Visual Studio Toolbox. To enable this under .NET you will need to reference the Telerik dlls via nuget. Installing the nuget packages will add the corresponding controls in the toolbox. Drag and drop from the toolbox is available only for the projects that have the Telerik nuget packages installed.
Additionally, the Telerik controls introduce customized design-time support as using smart tags, design-time selection, and also the standard control properties changing through the Visual Studio Designer
Creating a project via the Telerik Visual Studio Extensions, allows you to select a NuGet version and automatically add the packages in the project when created, thus adding the Telerik .NET controls into the Visual Studio Toolbox.
