Hi,

when using the beta-dlls with a custom theme (http://www.telerik.com/community/forums/wpf/scheduler/custom-theme-how-to-get-categories-working.aspx) the Visual Studio XAML-Designer stops working with the following error:

Error    181    Cannot convert the value in attribute 'Source' to object of type 'System.Windows.Markup.StaticExtension'.  Error at object 'System.Windows.Data.Binding', Line 1 Position 891.

Hi,

I solved it. It seems to be the same issue described here: http://blogs.msdn.com/delay/archive/2010/01/19/sometimes-it-takes-a-village-to-solve-a-problem-workaround-for-a-visual-studio-2008-design-time-issue-with-the-wpf-toolkit-when-blend-3-is-installed.aspx

uninstalling Blend 3 worked for me.
