ASP身份：渴望加载用户

Question

我在IdentityUser中添加了一个名为ClientID的属性，它与FK的表客户端正确相关。

现在我想用他的客户名称（来自Clients表）来检索用户。 如何在context.Users中创建Include函数？

    public ActionResult Users(string filter = "all")
    {

       context = new IdentityContext();
        var allusers = context.Users.ToList();

        List<UserViewModel> model = allusers.Select(user => new UserViewModel { Username = user.UserName,FullName=user.FirstName + " "+ user.LastName, Id = user.Id, Roles = string.Join(",", UserManager.GetRoles(user.Id))}).ToList();

        return View(model);
    }
