VS2015构建项目没有错误，CSC有错误CS1545

Question

我有一个c＃控制台应用程序，用于侦听NetworkInformation.NetworkStatusChanged事件：

using System;  
using Windows.Networking.Connectivity;  

namespace NetworkingConnectivityTest  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            try  
            {  
                NetworkInformation.NetworkStatusChanged += NetworkInformation_NetworkStatusChanged;  

                Console.WriteLine("Press any key to exit...");  
                Console.ReadKey();  

                NetworkInformation.NetworkStatusChanged -= NetworkInformation_NetworkStatusChanged;  
            }  
            catch ( SystemException e )  
            {  
                Console.WriteLine( "Main() exception: " + e.Message );  
            }  
        }  

        private static void NetworkInformation_NetworkStatusChanged( object sender )  
        {  
            try  
            {  
                ConnectionProfile inetCp = NetworkInformation.GetInternetConnectionProfile();  
                Console.WriteLine( "network information changed - internet connection profile: " + inetCp.ProfileName );  
            }  
            catch ( SystemException e )  
            {  
                Console.WriteLine( "NetworkInformation_NetworkStatusChanged exception: " + e.Message );  
            }  
        }  
    }  
}  

当我在VS2015（调试或发布）中构建它时，代码构建并按预期运行。

当我用VS2015开发工具命令提示符构建时，如下所示：
csc / nologo / noconfig / warn：4 .. \ program.cs ^
    / r：＆＃34; C：\ Program Files（x86）\ Reference Assemblies \ Microsoft \ Framework.NETFramework \ v4.5.2 \ System.dll＆＃34; ^
    / r：＆＃34; C：\ Program Files（x86）\ Reference Assemblies \ Microsoft \ Framework.NETFramework \ v4.5.2 \ mscorlib.dll＆＃34; ^
    / r：＆＃34; C：\ Program Files（x86）\ Reference Assemblies \ Microsoft \ Framework.NETCore \ v4.5.1 \ System.Runtime.WindowsRuntime.dll＆＃34; ^
    / r：＆＃34; C：\ Program Files（x86）\ Windows Kits \ 8.1 \ References \ CommonConfiguration \ Neutral \ Windows.winmd＆＃34;

我收到以下2条错误消息：
f：\ test \ networkingConnectivityTest \ program.cs（12,36）：错误CS1545：属性，索引器或事件＆＃39; NetworkInformation.NetworkStatusChanged＆＃39;语言不支持;尝试直接调用访问器方法＆＃39; NetworkInformation.add_NetworkStatusChanged（NetworkStatusChangedEventHandler）＆＃39;或者＆＃39; NetworkInformation.remove_NetworkStatusChanged（EventRegistrationToken）＆＃39;

任何帮助都非常感谢 - 提前感谢。
