style is not applied at runtime but being applied at design time in wpf

I have a simple style in a resource dictionary which is located in a WPFResources.dll, I am accessing this style in another project, I can see that the style is being applied at design time, but when i run the application I am getting an exception that "Cannot find resource named 'IndentCheckBoxStyle'. Resource names are case sensitive". if i use the StaticResource then I can see this exception if I use the DynamicResource then I dont see any exception, but nothing is visible on the UI.

More about this issue:

I have referenced the WPFResources.dll in my project and merged it in the App.XAML like this:

<Application.Resources>
    <ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/WPFResources;component/Theme.xaml" />
        </ResourceDictionary.MergedDictionaries>        
    </ResourceDictionary>
    </Application.Resources>

And inside the Theme.xaml i have merged the resource dictionary of the cheboxstyle.

Any one have any idea about this ??

Thanks in advance.

I've had this problem and found that the styles were being applied to the entire application using the Pack URI syntax,

e.g. in App.xaml

<Application x:Class="Framework.Presentation.Preview.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
         <ResourceDictionary>
             <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/Abt.Framework.Presentation;component/Themes/AbtDark.xaml"/>
            </ResourceDictionary.MergedDictionaries>
         </ResourceDictionary>
    </Application.Resources>
</Application>

However, an implicit style is not being applied to the top level window in the application (despite MyTheme.xaml containing an unnamed Style for Window)

To resolve this, I've simply used a named style (not implicit style) for the Window. The rest are applying correctly.
