Understanding UI for Xamarin and Linker Behavior


Platform Version
Xamarin.Forms Any
Xamarin.iOS Any
Xamarin.Android Any


When Xamarin.iOS or Xamarin.Android linker is set to Link All, Telerik code is being stripped out causing errors or run-time exceptions.


As the linker is a static tool, it can not plan for or include types and methods that are called through reflection, or dynamically instantiated. In short, if that type is not explicitly referenced in your project code, it will get removed by the linker.

You can take one of two options to resolve this:

Option 1 - Change Linker Behavior

This is our recommended approach. Change the linker behavior to strip out SDK assemblies only:

  • On Android, change the linker to SDK Assemblies Only
  • On iOS, change the setting to Link Framework SDKs Only

Option 2 - Define Skip Assemblies

If you must set the linker behavior to Link All, you can instruct the linker to skip certain assemblies. In this list, you can included any Telerik assemblies that is causing your errors.


For Xamarin.Android you can directly enter the assembly names into the Properties > Android Options tab's Skip Linking assemblies text box.

Alternatively, you can edit the csproj file and add the PropertyGroup manually:



For Xamarin.iOS, you need to pass a --linkskip argument in the Properties > iOS Build tab's Additional mtouch arguments text box..

--linkskip assemblyName1 --linkskip assemblyName2


For example, if you're getting a Missing Method Exception for Telerik.XamarinForms.Common.SomeMethod(), you can instruct the linker to skip that Common assembly.

On iOS it would look like this:

--linkskip Telerik.XamarinForms.Common

On Android, it would look like this:
