Hi,

I am creating a WCF service from scratch.
I am using this WCF service to hold my all business logic and data access logic.
If any one can help me to understand that what is the best practice or a best template to use for the same. I have heard about EF, UnitOfWork, Repository Pattern and Dependency Injection.
But I would like to have a template which use the best of them and help me understand and implement my service.

Thanks in advance
