WPF MahApps.Metro 资源未找到

Question

I updated the Packages recently and since then my recourses are not found anymore. Only the Controls and the Fonts are found but not the rest which i find really confusing. Did anyone had a similar problem? BR Max

This is a case of. when you upgrade a package, always check the documents for breaking changes

Migration to v2.0

Theming

The theming got rewritten, this means that there is no longer a separation between AppTheme and Accent. These got replaced by Theme everywhere. Instead of something like pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml and pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml you now have to use pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Blue.xaml.

New

<Application x:Class="WpfApplication.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

      </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
  </Application.Resources>
</Application>

_{Note : I don't use this package (or any of his stuff), there may be more to this story, however at least it might point you in the right direction. You need to read the rest of the documentation about migration}
