ASP.NET Identity - custom UserManager, UserStore

Question

I am a bit confused with customizing UserManager and UserStore. Out of the box solution comes with EF implementation and i don't want to use EF but my own DAL that uses MSSQL. I want to have Claims based security where one of the users Claims will be roles.

What i am confused with is the overall process i should do. From what i undestand so far is that i need to make my own

CustomApplicationUser : IUser
CustomUserManager : UserManager<CustomApplicationUser>
CustomUserStore : IUserStore, IUserClaimStore

Questions:

1. Am i on the right track with this?
2. I want to use IsInRole() method on my CustomUserManager but not sure how to do it with Claims. I am aware there is IUserRoleStore.IsInRole() which default UserManager calls in UserManager.IsInRole() but i don't want separate Roles table in my DB. What i want is Claims DB table with one of ClaimType being Role and that UserManager.IsInRole() uses that. Now, i am not evet sure why would i ever need UserManager.IsInRole() method? Would i actually need to have something like custom ClaimsIdentity SignInManager.CreateUserIdentityAsync() and within that one call my own implementation of filling in all users info including Claims?

It seems a bit confusing for me and i can't seem to find some clear documentation about it so if anyone could shed a bit of light on it i would highly appreciate it!

Instead of just copying I will just point you to following article: Overview of Custom Storage Providers for ASP.NET Identity.

Take a look at this, it should give you nice overview of how identity works in ASP.NET. It's also good for choosing what you want to override and customize in your application.
