WPF DataTemplate from another assembly

Question

Is it possible to reference DataTemplate which is located in another assembly in DataTemplateSelector.

Currently I have something like this:

public override DataTemplate SelectTemplate(object item, DependencyObject container)
    {
        var element = container as FrameworkElement;

        if (element != null && item != null && item is BrowserBaseViewModel)
        {
            return element.FindResource("BrowserDataTemplate") as DataTemplate;
        }
        return null;
    }

But it works only with current assembly.

Answer 1

Sure, write in your app.xaml a ResourceDictionary "include" so the dictionary can be found in your application.

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/MyOtherAssembly;component/MyAssemblyXaml.xaml" />

Now your data template will be found, because the resource lookup will look into the app.xaml resources, and find your referenced xaml.
