Merging resource dictionary into RibbonWindow makes backstage not show

Question

I'm seeing a strange behavior. If I add a merged dictionary of icons to a RibbonWindow.Resources, the backstage doesn't show. But if I add it to the Backstage.Resources (and not the RibbonWindow.Resources) it works.

Why does merging a dictionary into RibbonWindow.Resources interfere with the backstage?

I have attached a project that is demonstrating the problem.

I was able to work around this by adding the resource dictionary to app.xaml, but this should work.

Hi Walter,

While set the below code in code behind, the Backstage works with RibbonWindow.Resources . We attached demo for your reference.

Code:

SfSkinManager.ApplyStylesOnApplication = true;

Please let us know if you need any further assistance.
