Here is my ASP.NET MVC Project Strucure. (all are seperate projects)
1. FT.Web
2. FT.Entities
3. FT.BLL.Contracts
4. FT.BLL.Logic
5. FT.Data.Contracts
6. FT.Data.Sql

Here I'd like to create the Service Layer (contract and Logic) dependency in Web project. We can add contract project reference but not Logic Project since web project only required contracts not implementation.

I am able to do it by adding the Bll.Logic reference to Web Project but I dont like it since its tightly coupled with Web Project. Is there any other way that we can achieve the dependency without adding the reference? btw, I am using Unity.MVC3 for dependency Injection.

Dependency injection is not something you "add". This is not an ingredient, this is a design pattern... What's the problem?

Here is my code for Unity configuration

<?xml version="1.0"?>
<unity xmlns="">

    <!-- Services -->
    <typeAlias alias="IUserAccountService" type="FT.BLL.Contracts.IUserAccountService, Antony.BLL.Contracts" />
    <typeAlias alias="UserAccountService" type="FT.BLL.Logic.UserAccountService, Antony.BLL.Logic" />

    <register type="IUserAccountService" mapTo="UserAccountService" />

And Bootstrapper.cs code

private static IUnityContainer BuildUnityContainer()
          // var container = new UnityContainer();

           var section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
           IUnityContainer container = new UnityContainer().LoadConfiguration(section);

           // register all your components with the container here
           // it is NOT necessary to register your controllers

           // e.g. container.RegisterType<ITestService, TestService>();

           return container;

This configuration setting expects both service projects need to be added in Web project. But I just want to add Interface reference only. not implementation layer reference.
Thanks. Any Help.
