I want to merge one XAML file, that only contains styles into the Window.Resource of my application. I tried using MergedDictionaries as described in WPF Reference custom resource defined in another xaml file .
First: The File is named "MyStyleDocument.xaml" and contains different WPFstyles without using x-Keys.
 <ResourceDictionary 
   xmlns=" http://schemas.microsoft.com/winfx/2006/xaml/presentation "
   xmlns:x=" http://schemas.microsoft.com/winfx/2006/xaml ">
  <Style  TargetType="{x:Type TabControl}">
   (...)
  </Style>
  <Style  TargetType="{x:Type XY}">
   (...)
  </Style>
    .
    .
    .
</ResourceDictionary>
Second:
<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries> 
            <ResourceDictionary Source="MyStyleDocument.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>
I get the Result: "An error occurred while finding the resource dictionary "MyStyleDocument.xaml"." The file is located in the folder of my project.
My question is: How can I cleverly include one XAML file containing different styles into another XAML code?
The structure of my project is: WPFApplication(file folder1) -> File Folder1 includes WPFApplication(file folder2);WPFApplication.sln; WPFApplication.suo; WPFApplication.v11.suo File Folder 2 includes: bin (file folder2.1); obj(file folder2.2); Properties(filefolder2.3); App.xaml; App.xaml.cs; Application.ico; MainWindow.xaml.cs; MyStyleDocument.xaml; WpfApplication.csproj
