Hi Team

I have created Startup.cs file, but i have an error 'ApplicationSignInManager could not be found'. How do i solve this error, below is what i attempted so far.

What I have tried:

<pre>using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;
using Microsoft.Owin.Security.Cookies;
using Owin;
using eNtsaTrainingRegistration.Models;

namespace eNtsaTrainingRegistration
    public partial class Startup
        public void ConfigureAuth(IAppBuilder app)

// IdentityConfig.cs
public class ApplicationSignInManager:SignInManager<ApplicationUser, string>
         public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager)
         : base(userManager, authenticationManager)

         public override Task<ClaimsIdentity> CreateUserIdentityAsync(ApplicationUser user)
             return user.GenerateUserIdentityAsync((ApplicationUserManager)UserManager);

         public static ApplicationSignInManager Create(IdentityFactoryOptions<ApplicationSignInManager> options, IOwinContext context)
             return new ApplicationSignInManager(context.GetUserManager<ApplicationUserManager>(), context.Authentication);

Given your previous question today, are you sure the namespaces are correct?

Yes they are, what I did just now, first removed all dll under bin folder, clean and build solution. Still error, its still there so now im stuck. Usually issue its about using incorrect assembly, checked its correct.

In what namespace do you have ApplicationSignInManager class? What is the name of this namespace?

Mate I end up figure it out as you mentioned, googling it and find the answer and errors are gone. Richard you can close this thread mate.

Good! :)
Questions on CodeProject are not closed, they can only be solved (as far as I know).
I deleted my answer because I made a mistake, your problem was slightly different than I thought. Sorry about that mate.
