我正在为我的MVC5项目使用OWIN身份验证.这是我的SignInAsync

 private async Task SignInAsync(ApplicationUser user, bool isPersistent)
        {
            var AccountNo = "101";
            AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
            var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
            identity.AddClaim(new Claim(ClaimTypes.UserData, AccountNo));
            AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent, RedirectUri="Account/Index"}, identity);
        }

如您所见,我添加AccountNo到声明列表中.

现在,如何在我的应用程序中的某个时刻更新此声明？到目前为止,我有这个:

 public string AccountNo
        {

            get
            {
                var CP = ClaimsPrincipal.Current.Identities.First();
                var Account= CP.Claims.FirstOrDefault(p => p.Type == ClaimTypes.UserData);
                return Account.Value;
            }
            set
            {
                var CP = ClaimsPrincipal.Current.Identities.First();
                var AccountNo= CP.Claims.FirstOrDefault(p => p.Type == ClaimTypes.UserData).Value;
                CP.RemoveClaim(new Claim(ClaimTypes.UserData,AccountNo));
                CP.AddClaim(new Claim(ClaimTypes.UserData, value));
            }

        }

当我尝试删除声明时,我得到以下异常:

声明' http://schemas.microsoft.com/ws/2008/06/identity/claims/userdata:101 …

将asp.net身份版本1.0.0-rc1与Entity Framework 6.0.0-rc1(Visual Studio 2013 RC附带的那些)一起使用.

试图让用户有机会改变他们的UserName.似乎没有功能AuthenticationIdentityManager,所以我使用EF更改数据(获取当前用户的User对象,更改UserName并保存更改).

问题是认证cookie保持不变,下一个请求失败,因为没有这样的用户.

在过去的表单身份验证中,我使用以下代码来解决此问题.

var formsAuthCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
var isPersistent = FormsAuthentication.Decrypt(formsAuthCookie.Value).IsPersistent;
FormsAuthentication.SetAuthCookie(newUserName, isPersistent);

我该怎么做asp.net身份更新cookie？

UPDATE

以下代码似乎更新了身份验证cookie.

var identity = new ClaimsIdentity(User.Identity);
identity.RemoveClaim(identity.FindFirst(identity.NameClaimType));
identity.AddClaim(new Claim(identity.NameClaimType, newUserName));
AuthenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant
    (new ClaimsPrincipal(identity), new AuthenticationProperties {IsPersistent = false});

剩下的问题是:如何IsPersistent从当前身份验证cookie中提取值？
