asp.net – 缺少AuthenticationManager引用

跟进 this问题后,缺少SignOut()和SignIn()方法的引用：

private async Task SignInAsync(User user,bool isPersistent)
{
    AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
    var identity = await UserManager.CreateIdentityAsync(user,DefaultAuthenticationTypes.ApplicationCookie);
    AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent },identity);
}

有人知道如何解决它吗？

解决方法

您是如何定义AuthenticationManager属性的？通常它应该如下所示：

private IAuthenticationManager AuthenticationManager
{
  get
  {
    return HttpContext.GetowinContext().Authentication;
  }
}

有了它,您应该能够调用SignOut和SignIn方法.
