I'm coming mostly form a webforms background, working through the Little AspNet Core book (great book btw http://littleasp.net/book ). All was going well till I kind of messed up my migrations, and deleted the whole folder, and then did dotnet ef migrations add AddItems to create the AddItems migration. But there is supposed to also be a CreateIdentitySchema and CreateIdentitySchema.Designer migration that were created when you run dotnet new, only the project is no longer new. How do recreate these?

The author has a github but the files up there have a lot of other stuff that comes up in later steps that I want to do along with the tutorial when I get to it.
