    I am attempting to create the most basic page with a tab control. However, I am getting an error that says:
    "The tag 'RadTabControl' does not exist in XML namespace 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation'"

    My XAML is pretty simple. It looks like the following:

    <UserControl x:Class="MyProject.MyPage" 
        <Grid x:Name="LayoutRoot" Background="Silver"
            <navigation:RadTabControl x:Name="mainTabControl" /> 

    What am I doing wrong?

    Hi Frustrated Dev,

    Please find attached a sample project.
    Verify that you have referenced  under the Referense folder the following assemblies :
