Accessing resources in Xaml across projects/dlls

Question

Is it possible to reference Xaml assets stored in a ResourceDictionary (build action = resource) from another project? I would like to either merge the assets into the main project's resource dictionary or access them individual. For example:

Project "MyResources" contains a folder named "Assets" which has a ResourceDictionary called "MyAssets.xaml" which contains a Style called "ButtonStyle"
Project "MainProject" references MyResources; in MainWindow.xaml

In MainWindow.xaml I'd like to do something like:

<ResourceDictionary.MergedResources> <ResourceDictionary Source="/MyResources/Assets/MyAssets.xaml"/> </ResourceDictionary.MergedResources>

Or, if that's not possible, perhaps:

<Button Style="{StaticResource /MyResources/Assets/MyAssets.xaml}"/>

Is there a way to refer to stuff in MyResources from MainProject?

<ResourceDictionary Source="/Commons;component/Themes/TreeStyle.xaml" />

Where:

Commons is the name of the external project

/Themes/TreeStyle.xaml corresponds to the location of the style file in project Commons

;component is always required

And ensure there's no space between ; and component

According to ResourceDictionary in a separate assembly

<ResourceDictionary.MergedResources> <ResourceDictionary Source="pack://application:,,,/YourAssembly;component/Subfolder/YourResourceFile.xaml"/> </ResourceDictionary.MergedResources>

Thank you, my search should have turned that up. This is a dupe.

You can merge the resources from your project into your main dictionary using this method:

/// <summary> /// Loads a resource dictionary from a URI and merges it into the application resources. /// </summary> /// <param name="resourceLocater">URI of resource dictionary</param> public static void MergeResourceDictionary(Uri resourceLocater) { if (Application.Current != null) { var dictionary = (ResourceDictionary) Application.LoadComponent(resourceLocater); Application.Current.Resources.MergedDictionaries.Add(dictionary); } }

Call it like this:

MergeResourceDictionary(new Uri(@"/MyOtherAssembly;component/MyOtherResourceDictionary.xaml", UriKind.Relative));

Thanks for providing a code based answer as well, if I could have marked a second answer I would have!
