ASP.NET Core 2 and Angular 5

Upgrading the DbContext

In order to support the ASP.NET Core Identity service, our ApplicationDbContext class needs to be updated as well.

Open the Data/ApplicationDbContext.cs class file and perform the following changes:

1. Add a using reference to Microsoft.AspNetCore.Identity.EntityFrameworkCore, as required by the new base class:

using Microsoft.AspNetCore.Identity.EntityFrameworkCore; 

2. Change the base class from DbContext to IdentityDbContext<ApplicationUser>:

[...]public class ApplicationDbContext : IdentityDbContext<ApplicationUser> [...]

3. Remove the DbSet<ApplicationUser> Users property, as the IdentityDbContext base class that we just inherited already has it built in:

[...]#region Properties// public DbSet<ApplicationUser> Users ...
