Answer 1

Its only exposed on the EF implementation layer so:

roleManager.FindByName("Admins").Users

Answer 2

The accepted answer returns CustomUserRoles. If you are looking for the list of ApplicationUsers, try:

public IList<ApplicationUser> GetApplicationUsersInRole(string roleName)
{
    var selectedUserIds = from role in roleManager.Roles
                          where role.Name == roleName
                          from user in role.Users
                          select user.UserId;
    // this _users comes from the ApplicationDbContext.ApplicationUser
    return _users.Where(applicationUser => selectedUserIds.Contains(applicationUser.Id)).ToList();
}

I really liked VahidN's solution, but I modified it a bit. I made it into one query that uses the dbcontext. This allows you to add additional clauses into the query (e.g. deleted, emailconfirmed, etc.)

public IEnumerable<ApplicationUser> GetApplicationUsersInRole(string roleName)
{
      return from role in context.Roles
             where role.Name == roleName
             from userRoles in role.Users
             join user in context.Users
             on userRoles.UserId equals user.Id
             where user.EmailConfirmed == true
               && user.IsDeleted == false
             select user;
 }

I hope this helps! ~Cheers!
