In my environment, the problem is not happen.

Did you add MahApps Compatibility ResourceDictionary in App.xaml?

<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.MahApps;component/Themes/MaterialDesignTheme.MahApps.Defaults.xaml"/>

More information is needed.

@mey1k can you provide the versions of these NuGet packages that you are using?

mey1k commented 4 years ago

@Keboo @soi013 Thank you for your comments!

I solves this problem. I got a hint from your comments(dependencies).

Initially I installed it, ignoring the dependencies of the packages. Since then, the dependency was set, but the error continued to occur. So, I created a new project and after all the dependencies were set, it worked.
