I'm struggling with this issue for a few days. I guess it's something with solution because the same assemblies works fine for other projects.
Also in design time designer works okay and draw controls, but in runtime I'm getting System.Windows.Markup.XamlParseException.
Controls version is 2013.2.724.40 for .net 4.0,
Visual Studio 2013 with latest updates,
I have tried:
1) add references for assemblies in new solution and it works okay;
2) create new project(Wpf User Control Library and Class Library) in solution;
3) uninstall Microsoft.Bcl packages;
4) download latest trial version and even designer throw exception and intellisense didn't work for http://schemas.telerik.com/2008/xaml/presentation
in xaml ( <telerik: and empty list ).
So I have no idea what is going wrong... Could you help?
