Is this possible with Enterprise Libary 4.x? If so, can anyone point me to a decent tutorial about these 2 subjects. I am a newcomer to all this kind of stuff, also on Enterprise Library itself.

Nyla,

Dependency injection is possible using the Unity Application Block of the Enterprise Library.

Check the following MSDN page, which contains the required information about setting up the unity block.

Policy Injection is also supported by the Policy Injection Application Block.

Thank you for your reply. Do you know of some simple samples where it gets used? I am a bit of beginner on these topics but really want to learn as much as possible.

I suggest Googling for tutorial / articles if that is what you're looking for. E.g.:
