Question

I am following prism to build wpf application. In my application, there is a helper class library where I defined resources and styles which is going to be used by multiple class libraries in the solution.

But I am getting error when I try to set a resource to Style attribute of a window. The window is in differnt class library as of a resource.

The error that I am getting is :
Cannot find resource named ‘{resourceName}’. Resource names are case sensitive. Error at object ‘MyWindow’ in markup file

I used the following code but it is not working

<Window x:Class="Class1" Style="{StaticResource resourceName}">

<Window.Resources>    
        <ResourceDictionary>     
        <ResourceDictionary.MergedDictionaries>

       <ResourceDictionary Source="pack://application:,,,/classlibrary;component/Dictionary/resource1.xaml" />              </ResourceDictionary.MergedDictionaries>

    < /ResourceDictionary>

< /Window.Resources>
</Window>

You can use a pack URL to get a resource dictionary from another assembly. Check this thread.

Here is an example of a resource dictionary read from a Common assembly:

<Application.Resources> 
    <ResourceDictionary> 
        <ResourceDictionary.MergedDictionaries> 
            <ResourceDictionary Source="pack://application:,,,/Common;component/styles.xaml"/> 
        </ResourceDictionary.MergedDictionaries> 
    </ResourceDictionary> 
</Application.Resources>
