Question

I’d like to use Unity as an IoC container for an ASP.NET MVC 3 app but am having trouble with my UnityDependecyResolver class. It currently looks like this (copied from somewhere on the web as I don’t think Unity itself comes with this):

public class UnityDependencyResolver : IDependencyResolver
{
    readonly IUnityContainer _container;
    public UnityDependencyResolver(IUnityContainer container)
    {
        this._container = container;
    }
    public object GetService(Type serviceType)
    {
        try
        {
            return _container.Resolve(serviceType);
        }
        catch
        {
            return null;
        }
    }
    public IEnumerable<object> GetServices(Type serviceType)
    {
        try
        {
            return _container.ResolveAll(serviceType);
        }
        catch
        {
            return new List<object>();
        }
    }
}

However, I get this runtime error when trying to visit any controller:

The IControllerFactory ‘System.Web.Mvc.DefaultControllerFactory’ did not return a controller for the name ‘Account’.

This StructureMap article suggests that I should amend the GetService method, however, I’m quite new to both MVC and Unity and I’m not sure how exactly should it look like.

Have a look at the Unity.MVC project on codeplex.
