I use dotnet aspnet-codegenerator controller to create default views an controller for a model in area
My command: dotnet aspnet-codegenerator controller -name CartController -namespace AppMvc.Net.Areas.Cart.Controllers -udl -dc AppMvc.Net.Models.AppDbContext -outDir Areas/Cart/Controllers -m AppMvc.Net.Models.Cart.CartModel
When I run it: There is an error:
Exception of type ‘System.InvalidOperationException’ was thrown.

I inherit IdentityDbContext<AppUser> in appDbContext instead of DbContex
this error appear when I use IdentityDbContext<AppUser>
