我在从沙盒 Visual Web Part Sharepoint 2010 调用 Azure WCF 服务时遇到问题。所有本地计算机都安装了 Windows 7 64 Ultimate - Sharepoint Foundation 2010 以使用 Azure SDK 开发 Web 部件和 Visual Studio 2010。在本地 Azure 模拟器中启动的 Web 服务，本地计算机中的 Web 部件。当我使用标准主“添加服务引用”到 Web 部件时，生成 app.config，然后抛出错误：
ServiceReference1.Service1Client serv = new ServiceReference1.Service1Client();
Label1.Text = serv.GetData(9);
在 ServiceModel 客户端配置部分中找不到引用合同“ServiceReference1.IService1”的默认端点元素。这可能是因为没有为您的应用程序找到配置文件，或者因为在客户端元素中找不到与此合同匹配的端点元素。
当我以编程方式创建连接时 -
EndpointAddress adr = new EndpointAddress(new Uri("http://127.0.0.1:81/Service1.svc"));
BasicHttpBinding basic = new BasicHttpBinding();
ChannelFactory<ServiceReference1.IService1Channel> fact = new ChannelFactory<ServiceReference1.IService1Channel>(basic, adr);
Label1.Text = fact.CreateChannel().GetData(8);
抛出错误：
请求“System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089”类型的权限。
app.config 网页部分：

PS 当所有移动到工作部署 - Azure и Sharepoint Online - 再次出错。我以编程方式创建连接，因为读取，在沙盒解决方案 app.config 中未使用 Web 部件部署，我们必须在 web.config Sharepoint 2010 中复制他的代码 - 但在 Sharepoint Online 中，此文件已向开发人员关闭！
