Aps.net Identity 2.0 , Managing Roles

Hi,

I am creating a web form project (Not MVC) where i need to add manage roles pages and roles should be assigned to users. My task is to create roles , view roles in grid, edit roles, delete roles and assign roles to users.   These all is done old version of asp.net but in Asp.Net 4.5 i am not getting help and assistance.

I am using asp.net identity 2.0 and these below dlls

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.AspNet.Identity.Owin;

but i am able to do so.   For DB i am using Asp.net membership database. 

It will be really helpful to me , if someone did this work in asp.net 4.5 in web form project  and it must use Asp.net Identity 2.0 

Thanks In Advance.
