Using the error pipeline to capture and handle exception in a Nancy application

ErrorHandler.cs

    public class ErrorHandler : IStartup
    {
        public IEnumerable<TypeRegistration> TypeRegistrations
        {
            get { return null; }
        }

        public IEnumerable<CollectionTypeRegistration> CollectionTypeRegistrations
        {
            get { return null; }
        }

        public IEnumerable<InstanceRegistration> InstanceRegistrations
        {
            get { return null; }
        }

        public void Initialize(IPipelines pipelines)
        {
            pipelines.OnError += (context, exception) => {
                Debug.WriteLine("The following exception was captured: " + exception.ToString());
                return HttpStatusCode.InternalServerError;
            };
        }
    }

Home.cs

    public class Home : NancyModule
    {
        public Home()
        {
            Get["/"] = parameters => {
                return string.Format(
                    "Running, click <a href='{0}'>here</a> to throw an exception", 
                    this.Context.ToFullPath("~/exception"));
            };

            Get["/exception"] = parameters => {
                throw new NotImplementedException();
            };
        }
    }
