I have created a console application in Visual Studio 2010 and installed nuget packages such as Microsoft.Owin.Hosting and Microsoft.Owin.Host.HttpListener for OWIN and configured like below ``` namespace KatanaIntro { class Program { static void Main(string[] args) { const string uri = "http://localhost:8080"; using (WebApp.Start<Startup>(uri)) { Console.WriteLine("Started"); Console.ReadKey(); Console.WriteLine("Stopped"); } } } public class Startup { public void Configuraion(IAppBuilder app) { app.Run(ctx=> ctx.Response.WriteAsync("Welcome to my first katana application")); } } } ``` After running the application i got the exception EntryPointNotFoundException *The following errors occurred while attempting to load the app. - No 'Configuration' method was found in class 'KatanaIntro.Startup, KatanaIntro, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null* How can i resolve this?anything iam missing?
