The dll is either Store compliant or not - just add the dll to your references and see if it works. If it doesn't, then the dll would need to be rewritten to be Store compliant.

If my reply answers your question, please mark this post as answered.
NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.
