interfaces

I am using C# and I know what are the interfaces and how syntatically use them,etc. but what I have not learned yet is that when I am tasked to write a project, create a component,... How should I learn better about interfaces so when I want to do something I be able to Think about using them in my design...or for example I want to learn about dependency injection or even using mocking objects for testing, these are all related to good understanding of interfaces and know when and how to use them ... Can you plase provide me some good advice, reading,... then can help me with that?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language.

Do you need a good background in OOP before moving to frameworks?
