Why does this violate the type constraint?

Question

I\'m trying to customise ASP.NET Identity 3 so that it uses integer keys:

public class ApplicationUserLogin : IdentityUserLogin { }
public class Ap

Note for EF Core Users

Just to add to the above, if you are using .Net core 3.0 (not sure about earlier versions), there is no longer a AddEntityFrameworkStores method.

Instead there is a generic variant of IdentityDbContext so instead you derive your DbContext from IdentityDbContext

e.g. in my case

class ApplicationUser : IdentityUser {...}
class ApplicationDbContext : IdentityDbContext, int> {...}

then in your startup you can use services.AddDefaultIdentity
