    I've just updated the Silverlight Controls to the latest version, and after the end of the update I can't open the designer of one of the pages of my project. I can't recall everything that is in these pages, but the one that I can't see the designer has an RadChart on it, and none of the others, wich I can see on the designer, have it.

    I can edit the XAML code and compile and run that page, thought.

    Here's the exception details that come up when I open the designer:

    Method not found: 'System.String System.Environment.UnsafeGetFolderPath(SpecialFolder)'.
       at System.Windows.Application.CleanInBrowserAppDataCache()
       at System.Windows.Application.Application_Exited(Object sender, EventArgs e)
       at MS.Internal.CoreInvokeHandler.InvokeEventHandler(UInt32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
       at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)

    An unhandled exception was encountered while trying to render the current silverlight project on the design surface. To diagnose this failure, please try to run the project in a regular browser using the silverlight developer runtime.

    Thanks in advance!
