Required Assemblies for UWP Release Build

Environment

Product Version 2021.1 216.1
Product UI for Xamarin

Description

When the app is built in Release mode for UWP, you may experience issues like:

  • the border around Button, ComboBox, AutoCompleteView, Pickers is not visible

The reason behind this is that the .NET Native Toolchain strips the assemblies needed for visualizing the RadBorder control.

Solution

Make sure that the Telerik renderers are not stripped out by the UWP .NETNative compilation step.

Add the following code inside the App.xaml.cs file of the UWP Project:

var assembliesToInclude = new List<Assembly>()
{
    typeof(Telerik.XamarinForms.Input.RadButton).GetTypeInfo().Assembly,
    typeof(Telerik.XamarinForms.InputRenderer.UWP.ButtonRenderer).GetTypeInfo().Assembly,
    typeof(Telerik.XamarinForms.Primitives.RadBorder).GetTypeInfo().Assembly,
    typeof(Telerik.XamarinForms.PrimitivesRenderer.UWP.BorderRenderer).GetTypeInfo().Assembly,
};
Xamarin.Forms.Forms.Init(e, assembliesToInclude);
