SqlException: Invalid column name 'Discriminator'. Invalid column name 'Discriminator'. Invalid column name 'Discriminator'

问题

In ASP Dotnet Core While login/Register getting error

SqlException: Invalid column name 'Discriminator'. Invalid column name 'Discriminator'. Invalid column name 'Discriminator'.

Its showing error on

Areas.Identity.Pages.Account.LoginModel.OnPostAsync(string returnUrl) in Login.cshtml.cs
var result = await _signInManager.PasswordSignInAsync(Input.Email, Input.Password, Input.RememberMe, lockoutOnFailure: false);

if i use

[NotMapped]
public class ApplicationUser : IdentityUser{

}

then it solve my issue but again getting issue in List of users

InvalidOperationException: Cannot create a DbSet for 'ApplicationUser' because this type is not included in the model for the context.
