    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)
            {

                    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
