Where to place Business Logic classes in Entity Framework - ASP.NET MVC 4 solution?

I have a solution with one project - the Entity Framework and my ASP MVC project, I am looking for some tips or opinions on the idea of ​​creating at the top of my POCO and DBContext objects - a business logic level with static classes that have all methods (for example, a class ContactBLL with GetContactByID, GetAllContacts, GetContactsByType) to allow access to model data and which can be accessed in controller actions. Thus, I do not need to enter the implementation code of these methods into the Actions Controller methods, and it can be reused using these methods in other Action Controllers. I will be grateful for your opinion, because it can help me answer the question that I asked myself for about a week, based on the answer to this question (about where to determine the DBC context and how to use it).

You can create different projects in accordance with the main functions.

  • The data access level (context and DB repository, etc.) you can create Project.DataAccess, it will only have a class and db repository.

  • The business logic level (Project.Business) will have business logic and make a call at the data access level.

  • UI Layer (Project.WebUi) - mvc project. etc.

for details you can see this http://prodinner.codeplex.com/ code
