    I have Telerik for Silverlight Q1 2010 SP2 trial version installed and I created a new RadControls for Silverlight Application in VS 2010. After adding a book control from the RadControls for Silverlight group, building my application succeeded but running the application failed with error message "Unknown namespace http://schemas.telerik.com/2008/xaml/presentation." Can anyone shed some light on this?

    Thank you in advance,
    Noah

    Hi Noah,

    I see that you have downloaded the Silverlight 3 version of our controls and I am afraid that URI namespaces ("http://schemas.telerik.com/2008/xaml/presentation") are not supported in Silverlight 3. You could either upgrade to Silverlight 4, which I recommend, or use normal namespace mapping - for example xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"


    Sincerely yours,

    I have RadControls_for_Silverlight_4_2010_1_0603_TRIAL which as the name indicates is the latest version and for silverlight 4. I have also one issue when creating a new telerik C# silverlight application in visual studio 2010 in which there is only silverlight 3 option and no silverlight 4 option.

    I have solved the issue by installing Silverlight4_Tools for my vs 2010 where now I can see the silver light 4 version when I create a new Telerik silverlight application and running it works like a charm.
    Cheers,
