XamarinAndroid 中的错误“System.Net.Sockets.SocketException：System.Net.Sockets.SocketAsyncResult.CheckIfThrowDelayedException 处的连接被拒绝”

Question

我创建了一个 WCF 应用程序，它有 3 个方法来返回一些用户数据进行测试。我测试过没有问题。 我在 Xamarin 中添加了 Web 参考，但是当我想使用该方法时，它出现错误异常。

WCF web.config

        <add name="ServiceConnection" connectionString="Data Source=.;Initial Catalog=StoreDb;Integrated Security=true;" providerName="System.Data.SqlClient"/>
    </connectionStrings>
</configuration>

这是我在 Xamarin android 中使用 C# 的代码

localhost.MyStoreService service = new MyStoreService();
            var user = service.UserGetById(1, true);


            label.Text = user.FName;

这就是错误异常
