Unity in Prism using WPF

In Prism can we have another instance of unity at module level to register the classes in a particular module.so that i will not load the application level unity with so many classes in different modules.

• I think what you are looking for is a scoped unity container. Here's an article on it: http://blogs.microsoft.co.il/blogs/gilf/archive/2008/07/26/using-unity-container-hierarchies.aspx

  This would allow your users to get all of the types registered in the "Parent" container, but also allow them to add their own without affecting the "Parent" container.
