Following tutorials such as Host UWP XAML Controls in desktop apps (XAML Islands), I can add Microsoft UWP controls to WPF apps. Based on the doco, it appears third party and custom UWP controls can also be used like this.
What do I need to do to add 3rd party UWP controls to wpf desktop apps? Specifically, I am interested in using Telerik's open source UI for UWP controls.
I have added the Telerik nuget package to my uwp project, and have the XamlHost in my WPF project but where I try to code a control the ui instead shows a message Cannot create control of type Telerik.UI.XamlControls.<ControlName>.
Can someone show the way to use (for e.g.) the Telerik UWP Rad Gauge in a WPF desktop app with XAML Islands?
