    Hello Ravi,

    The problem is probably due to a missing reference or wrong version of an assembly.
    Please check those, try deleting bin, obj and rebuilding. A list of all required assembly references can be found here.
    Hope this helps you.

    I am encountering a similar error for a wpf application that supports netcoreapp3.1 and net472.  It works when running under net472(Telerik version: 2017.1.222.45) but fails when running necoreapp3.1(Telerik version: 2020.1.218.310).  I removed the bin and obj folders and rebuilt but the error is still there.  

      Message='Initialization of 'Telerik.Windows.Controls.RadComboBox' threw an exception.' Line number '419' and line position '10'.

    Hi Jose,

    It seems that the references are missing and the control cannot be initialized. Please note that we have a separate set of assemblies for .NET Core. Make sure that the correct assemblies are referenced in your project. The assemblies for net core are located in the following folder: C:\Program Files (x86)\Progress\Telerik UI for WPF R1 2020\Binaries\NetCore. In addition, their version ends with 310.

    I hope this helps. Should you have any other questions do not hesitate to ask.
