The entity type 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityUserLogin<string>' requires a key to be defined

Question

All was working fine until I introduced Identity.

I changed my context class to be:

public partial class VisualJobsDbContext : IdentityDbContext<ApplicationUser>
{
    private IConfigurationRoot _config;

    public VisualJobsDbContext() { }

    public VisualJobsDbContext(IConfigurationRoot config, DbContextOptions options) : base(options)
    {
        _config = config;
    }...

and I have a Generic repository that is declared in the form:

public abstract class GenericRepository<C,T> : IGenericRepository<T> where T : class where C : IdentityDbContext<ApplicationUser>, new() 
{
    private C _entities = new C();
    private VisualJobsDbContext context;
    private DbSet<T> dbSet;

    public GenericRepository(VisualJobsDbContext context)
    {
        this.context = context;
        this.dbSet = context.Set<T>();
    }....

The Error occurs on the

this.dbSet = context.Set<>();

the first time it gets hit. My OnModelCreating method does get called. The page I'm trying to get to from my MVC app does not require a login as it is a general page, but there will be areas that will require a login. However, I dont get as far as my controller Constructor method before it errors. To Register the service I have:

services.AddIdentity<ApplicationUser, IdentityRole>()
            .AddEntityFrameworkStores<VisualJobsDbContext>()
            .AddDefaultTokenProviders();

and I can step this ok.

any ideas what I'm missing? I have looked at this stackoverflow answer and others, but it doesn't really help

Answer 1

In my OnModelCreating Method. I needed to place base.OnModelCreating(modelBuilder); as my first line of code.
