我是 asp.net core 的新手，我使用 Identity Core 使用 Asp.Net Core 2.2 +EF 创建了一个应用程序来创建注册页面，在运行应用程序并引入一些测试数据（电子邮件、密码）后出现此错误:
SqlException: Invalid column name 'NormalizedUserName'.
Invalid column name 'AccessFailedCount'.
Invalid column name 'ConcurrencyStamp'.
Invalid column name 'Email'.
Invalid column name 'EmailConfirmed'.
Invalid column name 'LockoutEnabled'.
Invalid column name 'LockoutEnd'.
Invalid column name 'NormalizedEmail'.
Invalid column name 'NormalizedUserName'.
Invalid column name 'PasswordHash'.
Invalid column name 'PhoneNumber'.
Invalid column name 'PhoneNumberConfirmed'.
Invalid column name 'SecurityStamp'.
Invalid column name 'TwoFactorEnabled'.
Invalid column name 'UserName'.
我创建了一个表，但没有像上面那样命名的列（我的列只有“电子邮件地址”和“密码”）

@AlexGodo 我知道这个主题已经过时了，但它可能会帮助那些不想使用迁移而只想连接到现有
AspNet*AspNetUsers我缺少 4 列，其中
NormalizedUserNameNormalizedUserName nvarchar(256), null
NormalizedEmail nvarchar(256), null
LockoutEnd datetime, null
ConcurrencyStamp nvarchar(256), null
为了能够登录，我运行了更新来填充 NormalizedUserName 列，如下所示：
update AspNetUsers
set NormalizedUserName = UPPER(Email)
where NormalizedUserName is null
注意： 通过 ASP.NET Core 网站登录后，
PasswordHash希望这有帮助。
当您搭建
Identity如果你不想使用这些外部列，又想继承Identity，你可以声明列名（public string NormalizedName {get;set;}）并在其上方添加[NotMapped]，因此实体框架将忽略希望这有帮助
