    Hello Al,

    Such errors commonly appear if the project references mixed version of the Telrik dlls (normal and Xaml). Please double check if you are using only one version. You can read more about NoXaml in the Setting a Theme help article. Also, you can try to manually delete the "bin" and "obj" folders of your project, restart Visual Studio, and then Clean/Rebuild the project. 

    Regards,
    Martin
