    I have been using the SL controls for a while and have not installed anything lately that i could think of is causing this

    First thing i noticed was that silverlight controls did not appear in the Telerik menu. All other extensions (ASP.NET, MVC, etc) are there

    i then tried to create a new project (Telerik C# Silverlight ) and get the error in the attached screenshot

    i then reinstalled RadControls_for_Silverlight_4_2011_1_0419_Dev.msi

    after reinstalling i still had the same problems (the samples run btw)

    then i came across the post about the 'Telerik Silverlight VS Extensions' and thought i'd try to install it

    it showed me the following error messages during install

    i tried to uninstall using the VStudio Tools->Extension Manager (VS run as administrator). i can uninstall most telerik extensions except for the silverlight one. it says you have to remove via add/remove programs

    problem is it is not visible in add/remove programs at all

    any idea how to get my ide to play nice with radcontrols again ?

    thanks

    Mike

    i manually removed all telerik files in the vstudio extension folders and removed all traces of telerik in the xml files and was then able to install the VSExtensions

    looks like it might be working now
