I added the xceed Windows 10 theme to my wpf application. If I now want to open a Xceed Toolkit MessageBox, an error appears: InvalidOperationException on PresentationFramework.dll
– DependencyProperty.UnsetValue is not a valid value for property foreground.
Other xceed themes like office 2007 works. What about Xceed Windows 10 theme?
Are you using the plus or the community edition. If you are using the plus edition, could you send me a simple stand alone sample project which reproduces the issue so that I could have a closer look. You may send it to firstname.lastname@example.org
