In a silverlight application you have App.xaml, but in a Silverlight library you don't. I tried using generic.xaml but I think this serves the specific purpose of applying styles to all controls based on their type. In case, I just want a place to put things like paths or objects that I will reuse throughout the library.
A:
Take a look at the Silverlight Toolkit's SharedResources.cs file, it's a little hacky but may help with your scenario.
It isn't the same as sharing XAML resources, but it may help you get access to images and other embedded content types.
