C# 将Windows Phone 8.1应用商店应用程序连接到现有Azure SQL数据库

我正在写一个WindowsPhone8.1商店应用程序来帮助管理我所在小镇的公共交通，作为我大学的一个项目

教授让我创建这个应用程序，实现一个Web服务和一个SQL数据库

经过一些研究，我决定使用WindowsAzure和SQL数据库。数据库只包含一个简单的表，其中包含公共汽车站（每个表都有一个Id、名称、纬度和经度）

如果我执行一个查询，我对结果没有问题。然而，问题开始了，然后我尝试将我的项目连接到Web服务&关联的数据库

按照Microsoft教程中的建议，我在项目中创建了che客户端，如下所示：

public static Microsoft.WindowsAzure.MobileServices.MobileServiceClient RapalloBusClient = new Microsoft.WindowsAzure.MobileServices.MobileServiceClient(
        "https://<mywebservicename>.azure-mobile.net/",
        "xxxxxxxxxxxxxxxxxxxxxxxxxxxx");

Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException non è stata gestita dal codice utente
  HResult=-2146233079
  Message=The request could not be completed.  (Internal Server Error)
  Source=Microsoft.WindowsAzure.Mobile

  InnerException: 

这段代码正在生成一个错误（“内部服务器错误”或“未找到”），我无法找出它错在哪里

我在下面的链接中使用了教程，附带了解决方案，我没有遇到任何问题

编辑：

我使用visual studio中的

MobileServiceMobile

项目的设置将移动服务连接到数据库（在“Pubblicazione/Creazione pacchetto SQL”部分（意大利语）中，我选中“从现有数据库提取数据/模式”选项，从Azure提供数据库url）

我删除了断点，让应用程序运行，但当我执行以下行时，我在异常中运行：

fermate = await fermateTable.ToCollectionAsync();

例外情况如下所示：

public static Microsoft.WindowsAzure.MobileServices.MobileServiceClient RapalloBusClient = new Microsoft.WindowsAzure.MobileServices.MobileServiceClient(
        "https://<mywebservicename>.azure-mobile.net/",
        "xxxxxxxxxxxxxxxxxxxxxxxxxxxx");
