Register OpenIddict entities into DbContext in another way

Question

Is there another way to register the entity sets needed by OpenIddict onto a DbContext except calling options.UseOpenIddict(); in services.AddDbContext<OpenIdDictDbContext>(options => {...}).

I have trouble with this approach, because I have more DbContexts, and I want to share DbContextOptions.

In .Net Core 2, if you can use non generic DbContextOptions for all DbContexts OR you must have nongeneric DbContextOptions<T> for all DbContexts. So, I would like the first approach if it possible.

You can directly register the OpenIddict entities from OnModelCreating:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext(DbContextOptions options)
        : base(options) { }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        // Register the entity sets needed by OpenIddict.
        // Note: use the generic overload if you need
        // to replace the default OpenIddict entities.
        builder.UseOpenIddict();

        // Customize the ASP.NET Identity model and override the defaults if needed.
        // For example, you can rename the ASP.NET Identity table names and more.
        // Add your customizations after calling base.OnModelCreating(builder);
    }
}

If you don't see the extension, make sure you have a Microsoft.Extensions.DependencyInjection using and that your project references OpenIddict.EntityFrameworkCore.
