C# Xamarin表单PCL项目出现Azure移动服务错误

我试图在Xamarin Forms PCL项目中使用Azure移动服务，但遇到了无法解决的错误

我在这一点上遵循了Azure的官方文档

****理由****

我已经从NuGet软件包安装了Windows Azure移动服务，并将CurrentPlatform.Init；&使用Microsoft.WindowsAzure.MobileServices；在每个平台上。 下面是我发现的一些教程，可以在Xamarin表单中实现Azure移动服务。我试过了，但还是不起作用。这是链接--> 1, 2, 3 以下是我的项目代码：

错误消息非常明确-表'restaurant'不存在-您确定它存在于您的数据中吗？我也有同样的问题，我必须在Azure UI中手动创建表，因为它不会动态创建它。

using eRestaurant.Model;
using eRestaurant.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection.Emit;
using System.Text;
using Xamarin.Forms;

namespace eRestaurant
{
    public class RestaurantPage : ContentPage
    {
        RestaurantViewModel viewModel = new RestaurantViewModel();
        ListView RestaurantListView = new ListView();

        public RestaurantPage()
        {
            Title = "Restaurants";
            Style = AppStyle.PageStyle;
            RestaurantListView.RowHeight = 40;

            RestaurantListView.ItemsSource = viewModel.restaurantData;
            RestaurantListView.ItemTemplate = new DataTemplate(typeof(RestaurantViewCell));
            Content = RestaurantListView;
        }
    }
}

using System;
using System.Collections.Generic;
using System.Diagnostics;
using Microsoft.WindowsAzure.MobileServices; //Azure Mobile Service
using System.Threading.Tasks; //For multithreading
using eRestaurant.Model;

namespace eRestaurant.ViewModel
{
    public class RestaurantViewModel
    {
        private IMobileServiceTable<Restaurant> restaurantTable;

        const string applicationURL = @"https://erestaurant.azure-mobile.net/";
        const string applicationKey = @"MyApplicationKey";

        MobileServiceClient client = new MobileServiceClient( applicationURL, applicationKey);


        public IEnumerable<Restaurant> restaurantData;

        public RestaurantViewModel()
        {
            GetData ();
        }

        public async void GetData(){
            restaurantTable = client.GetTable<Restaurant> ();
            restaurantData = await restaurantTable
            .Where (restaurant => restaurant.RestaurantName != null)
            .ToListAsync ();
        }

    }
}

using System;
using Xamarin.Forms;
using System.Collections.Generic;
using eRestaurant.Model;

namespace eRestaurant
{
    public class RestaurantViewCell : ViewCell
    {
        public RestaurantViewCell()
        {    
            Label restaurantName = new Label();
            restaurantName.Style = AppStyle.RestaurantLabelStyle;

            Label tag = new Label();
            tag.Style = AppStyle.TagLabelStyle;

            restaurantName.SetBinding(Label.TextProperty, "RestaurantName");
            tag.SetBinding(Label.TextProperty, "Tag");

            StackLayout nameLayout = new StackLayout()
            {
                HorizontalOptions = LayoutOptions.StartAndExpand,
                Orientation = StackOrientation.Vertical,
                Children = { restaurantName, tag }
            };

            View = nameLayout;
        }
    }
}
