When dragging and dropping a control from the Visual Studio (VS) Toolbox onto the Form Designer, VS automatically adds the necessary assemblies. However, if you're adding the control programmatically, you'll need to manually reference the following assemblies:

  • Telerik.Licensing.Runtime
  • Telerik.WinControls
  • Telerik.WinControls.UI
  • TelerikCommon
