resolving pack uri not working in wpf

Question

Although I've found a lot of "pack uri issue" questions, I didn't get an answer for my problem.

I have a prism solution where I want a MyApplication.Resources assembly hold all my application wide styles and templates.

So

• Step 1: I've created the solution (WpfUsercontrollibrary)
• Step 2: folder /Themes was created
• Step 3: Generic.Ribbon.xaml was created
• Step 4: Generic.xaml was created
• Step 5: Generic.xaml has a MergedDictionary part to merge all the Generic.xxx.xaml files
• Step 6: MyApplication.Resources assembly referenced in prism module assembly

• Step 7: loading the Generic.xaml in my module view (type: Microsoft.Windows.Controls.Ribbon.RibbonTab

  <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
          <ResourceDictionary Source="/MyApplication.Resources;component/Themes/Generic.xaml"/>
      </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>
  

I've also tried the absolute variant with

<ResourceDictionary Source="pack://application:,,,/ElairoCRM.Resources;component/Themes/Generic.xaml"/>

All steps above are verified with the MSDN doku to pack uri and a lot of stackoverflow questions and wpf resource tutorials in the internet.

But nothing works. Did I miss something?

Thank you in advance.

Edit: I've forgot the error that occured:

XamlParseException with inner exception FileNotFoundException having the message: The file or assembly \"MyApplication.Resources, culture=neutral" or one of its dependencies, was not found.

Answer 1

I've resolved the problem by myself. I copied the Generic.xaml file in the Resource assembly from the themes folder to the assembly root and changed the pack argument to component/Generic.xaml. Everything works now as expected. I've found no documentation about this behaviour.
