    using Microsoft.AspNet.Identity;
    using Microsoft.Owin;
    using Microsoft.Owin.Security.Cookies;
    using Owin;

    [assembly: OwinStartup(typeof(WebFormsIdentity.Startup))]

    namespace WebFormsIdentity
    {
    public class Startup
    {
    public void Configuration(IAppBuilder app)
    {
    // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=316888
    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
    LoginPath = new PathString("/Login")
    });
    }
    }
