MVC .NET C# school project web site authorization with my tables

I got 2 projects done in MVC, one with code first approach, other with db first. I want authorization of my code first to be by using my tables, and not with AspNetRoles, ASPNetUserRoles and other automatically generated tables. For someone who knows what he is doing this should be easy under 15 minutes work. Here are the 2 projects i mentioned: DB first: [login to view URL]!myo0UCSQ!yv1Q8zlbtK5-ncWHIftD4sTtf2kY9WqG5AqhUp1vq48 Code first: [login to view URL]!mvpyxQIY!AxcVZ2EMPdVw4rnh_TnibKAQ_elvjoM3IJDQD-8bUkQ I need to have same kind of authorization like it is in DB first project implemented into Code first project.
