由于数据库会检查模型兼容性，因此无法检查

Question

身份mvc 5中存在问题：当用户想要查看我的控制器时，我使用[Authorize（Roles =“ Admin”）]仅登录管理员角色。 因此，当用户重定向到登录页面并进行登录时，此错误将显示：

Model compatibility cannot be checked because the database does not contain model metadata. Model compatibility can only be checked for databases created using Code First or Code First Migrations.

Description: An unhandled exception occurred during the execution of the current web request.         Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.NotSupportedException: Model compatibility cannot be checked because the database does not contain model metadata. Model compatibility can only be checked for databases created using Code First or Code First Migrations.

Source Error: 


Line 73:             // This doen't count login failures towards lockout only two factor authentication
Line 74:             // To enable password failures to trigger lockout, change to shouldLockout: true
Line 75:             var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
Line 76:             switch (result)
Line 77:             {

我的用户是管理员，但我不知道有关此错误的任何信息，值得注意的是，我通过nuget使用Asp.Net身份示例。

我通过从数据库中删除身份表解决了我的问题，并重建了项目，然后再次运行并创建新用户以再次创建表，因此问题已得到解决！
