New Post: Integrating IoC + DI

I'm studying Composite C1 to integrate an existing application.
The application has several years and many parts will initially be reused as much as possible while keeping unchanged the code and logic.
Most likely I will adopt the functions of composite C1 with the user control to simulate the operation of the old pages and some new parts using the MVC framework to expose APIs that return JSON data.
How can I integrate Ioc and DI provided by Unity in Composite C1 for my user control and functions?

Thanks in Advance.
