Commented Issue: 'Initialization of 'Xceed.Wpf.Toolkit.RangeSlider' threw an exception in VS2015 CTP6 [21739]

Since installation of Visual Studion 2015 CTP6 RangeSlider gives as runtime error:

{"'Initialization of 'Xceed.Wpf.Toolkit.RangeSlider' threw an exception.' Line number '87' and line position '189'."}

{pack://application:,,,/Coolblue.Purchasing.CompetitorPricing;component/views/elasticitysettingsview.xaml}

{"Initialization of 'Xceed.Wpf.Toolkit.Core.VersionResourceDictionary' threw an exception."}

{"Cannot locate resource 'xceed.wpf.toolkit;v2.3.0.0;themes/xceed.wpf.toolkit;v2.3.0.0;component/themes/aero/brushes_normalcolor.xaml'."}

This did not happen before in Visual Studio 2015 Preview.

Dit something change in VS2015 CTP6 that broke this?

Thanks in Advance for any answers,
Antoni Dol

Same issue here with all WPF Toolkit controls.
When can we expect this critical bug to be fixed in the Community Edition (I guess it wouldn't make sense to artificially delay it)?
