Question

I\'m using a class library that can be reused by other components. In this class library I\'m using unity for dependency injection. For this class library I create a test pr

O.K Create a library named Project.Ioc. Install Unity here. Reference the other layers to Ioc library. And Ioc Library to presentation layer. Create a class named UnityHelper.

/// 

/// Bind the given interface in request scope
/// 
public static class IocExtensions
{
    public static void BindInRequestScope(this IUnityContainer container) where T2 : T1
    {
        container.RegisterType(new HierarchicalLifetimeManager());
    }

    public static void BindInSingletonScope(this IUnityContainer container) where T2 : T1
    {
        container.RegisterType(new ContainerControlledLifetimeManager());
    }
}

/// 

/// The injection for Unity
/// 
public static class UnityHelper
{

    public static IUnityContainer Start()
    {
        var container = BuildUnityContainer();

        DependencyResolver.SetResolver(new Unity.Mvc4.UnityDependencyResolver(container));

        return container;
    }

    /// 

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

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

        // Database context, one per request, ensure it is disposed
        container.BindInRequestScope();
        container.BindInRequestScope();

        //Bind the various domain model services and repositories that e.g. our controllers require         
        container.BindInRequestScope();

        container.BindInRequestScope();

        //container.BindInRequestScope();

        return container;
    }
}

Check out the MvcForum project. There is MvcForm.Ioc class library. The library gets other Layer references. There are only one class named UnityHelper.
