'ApplicationDbContext.RoleClaims' hides inherited member 'IdentityDbContext<IdentityUser, IdentityRole, string, IdentityUserClaim<string>, IdentityUserRole<string>, IdentityUserLogin<string>, IdentityRoleClaim<string>, IdentityUserToken<string>>.RoleClaims'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

'ApplicationDbContext.Roles' hides inherited member 'IdentityDbContext<IdentityUser, IdentityRole, string, IdentityUserClaim<string>, IdentityUserRole<string>, IdentityUserLogin<string>, IdentityRoleClaim<string>, IdentityUserToken<string>>.Roles'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

'ApplicationDbContext.Users' hides inherited member 'IdentityUserContext<IdentityUser, string, IdentityUserClaim<string>, IdentityUserLogin<string>, IdentityUserToken<string>>.Users'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
