High contrast theme is not getting applied

We want to add the possibility to use the Default Windows Theme in the Apps generated by Windows Template Studio and support High contrast.

Adding the sync option was quite straight forward, but we’re having trouble implementing High Contrast support. You can find a repro project at https://github.com/sibille/WTS.WPF.HighContrastSupport. Are we missing something?

Problems we are facing:

1. When selecting “Windows default”, I can see a the following theme getting applied in the OnThemeChanged event {DisplayName=Runtime #C400B7C3 (Light) HighContrast, Name=Light.Runtime_#C400B7C3, IsHighContrast=True, IsRuntimeGenerated=True} but no colors do seem to change.

2. When selecting Dark or Light the OnThemeChanged event does not get fired.

Other questions:

• Do we need to add a custom high contrast theme for Dark/Light High Contrast support ?
• Do we need to explicitly set the high contrast theme using ThemeManager.Current.ChangeTheme?

@sibille That’s a bug in ControlzEx. Will have a look and fix it. I forgot some cases inside SyncTheme when i added high contrast support.

Thank you both!
