The process to get all roles via setting up ApplicationRoleManager is the following (as per Identity samples provided by Microsoft found here).

Add the code below to your IdentityConfig.cs

public class ApplicationRoleManager : RoleManager<IdentityRole>
{
    public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore)
        : base(roleStore)
    {
    }

    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        return new ApplicationRoleManager(new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>()));
    }
}

Then initialize the single instance per Owin context of your RoleManager in Startup.Auth.cs:

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

In your controller where you want to get all roles, do the following:

private ApplicationRoleManager _roleManager;
public ApplicationRoleManager RoleManager
{
    get
    {
        return _roleManager ?? HttpContext.GetOwinContext().Get<ApplicationRoleManager>();
    }
    private set
    {
        _roleManager = value;
    }
}

After that you can simply use RoleManager.Roles in any of your action methods to get all roles.

This answer contains all the steps you need to get this to work but refer to the link to the nuget package above if you're still unclear on the process.
