Commented Unassigned: '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

Hi,

I just tried the following sample :
```
<StackPanel>
<xctk:IntegerUpDown Value="35" />
<xctk:ColorPicker SelectedColor="Blue"/>
<xctk:RangeSlider Minimum="0" Maximum="100"/>
<xctk:WatermarkTextBox Watermark="Testing"/>
</StackPanel>
```
and it worked without any exceptions.
Here are the setting I used :
-Windows 8.1
-VisualStudio 2015 RC , Version 14.0.22823.1 D14REL
-Target Framework : .NET Framework 4.6 (.NET Framework 4.5.2 also worked)
-Xceed.Wpf.Toolkit v2.4.
