我一直在试验 MVC5/EF6 并尝试使用代码优先迁移进行新的身份验证。解决方案中的所有内容目前都在构建，我可以添加 Migration ，但是当我通过 VS2013 中的 update-database 执行 package manager console 时，我的 Configuration.cs 文件无法将我的测试数据完全处理到我的表中并输出 Error Adding User to Role: UserId not found 。
我曾尝试明确设置一个用户 ID 并将其留给管理器生成(如某些示例所示)，但每次我都收到相同的错误消息。我知道错误在我的 #region User & User Roles 文件的 Configuration.cs 中失败了，但我不确定为什么:

任何人都可以在这里提供一些我可能忽略的见解吗？有关详细信息，我当前的 catch 语句输出以下内容:
Error Adding User to Role: UserId not found.
System.Collections.ListDictionaryInternal
Name: Admin User
Email: Admin@abc.com
user.ID: 1
u.Id: 1
Role: Root
CodeHit: True
当我为管理员用户注释掉显式 Id = "1", 时，user.ID 和 u.Id 变为: ab753316-3d7b-4f98-a13a-d19f7c926976 。我原以为问题可能出在我的 GetTestUsers() 或 GetUserRoles(u.Email) 辅助方法上，但在我的 try/catch 和我正在使用的 codeHit bool 变量之间，我已经验证问题肯定来自 manager.AddToRole(user.Id, role) 。
最佳答案
我将此留给可能有类似问题的任何人。我有完全相同的“症状”。事实证明，问题与存储的密码不符合配置的密码策略(至少一个大写字符、一个小写字符等)有关。
根据下面的评论和答案，一般来说，如果不遵守任何用户创建约束或策略，则会抛出相同的模糊错误消息。
这可能包括以下内容:
- 未遵守密码政策(这似乎是最常见的原因)
- 必填字段作为空字符串/null 传递
- 重复的用户名或电子邮件
确实有很多问题会导致此错误发生。如果以上不能解决您的问题，我建议如下:
- 熟悉为您的解决方案设置的 identityprovider 的规则和政策
- 按照下面@Ted 的回答，跟踪或在 UserManager.Create 方法上设置断点以查看结果，因为这可能会揭示问题的原因。
