Hello I want to add role based authentication for my aspnetcore2.0 + postgresql project. for this reason I followed How to create roles in asp.net core and assign them to users
but I get error
Cannot create a DbSet for 'IdentityRole' because this type is not included in the model for the context
by the way, I dont have identityrole and identityuser tables in my db table.
the simple project can be downloaded from http://eticaret.turkalpkucur.com/katmanliproje2.rar
