C# 在Xamarin应用程序中实例化CloudStorageAccount会导致未处理的异常

在下面的文章中，我创建了一个空白的Xamarin表单应用程序，将

WindowsStorage.Azure

包添加到PCL和Android应用程序中（我已经删除了iOS和UWP，因为它只是一个测试应用程序）

或新的CloudStorageAccount：

var storageAccount = CloudStorageAccount.Parse(storageConnectionString);

我也一样。 我通读了这本书，看不出有什么原因

有没有人遇到过这个问题，可以帮助我们找出哪里出了问题

编辑：

我可以从debu窗口看到它抛出了一个NotImplementedException：

回复：第3步

Azure Storage使用本机功能，因此您不仅需要在PCL项目中安装该软件包，还需要在每个本机应用程序项目中安装该软件包。
请查看调试/输出窗口以了解有关错误的详细信息。有时，您确实需要点击“继续”按钮才能显示此内容。但是随便猜测一下（没有任何进一步的信息），除了pcl之外，您是否已将azure存储包添加到您正在启动的本机中。
var storageAccount = CloudStorageAccount.Parse(storageConnectionString);
