在MVC5Framework4.7.1中，在哪里设置标识‘SetLockoutEndDate

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
        
        // Configure lockout settings
        manager.UserLockoutEnabledByDefault = true;
        manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
        manager.MaxFailedAccessAttemptsBeforeLockout = 5;

        // Configure user lockout
        manager.UserLockoutProvider = new DefaultUserLockoutProvider<ApplicationUser>
        {
            // Set lockout end date
            OnLockoutEnd = (u, t) => u.SetLockoutEndDate(t)
        };

        return manager;
    }
}
