    using Nancy;

    public class IndexModule : NancyModule
    {
        private readonly IFoo foo;

        public IndexModule(IFoo foo)
        {
            this.foo = foo;
            Get["/"] = DoSomething;
        }

        private dynamic DoSomething(dynamic parameters)
        {
            return foo.GetMessage();
        }
    }

    public interface IFoo
    {
        string GetMessage();
    }

    public class DefaultFoo : IFoo
    {
        public string GetMessage()
        {
            return "Hello world";
        }
    }
