Question

在this篇文章之后，我创建了一个空白的Xamarin表单应用，将WindowsStorage.Azure包添加到了PCL和Android应用中（我现在删除了iOS和UWP）它只是一个测试应用程序）

  <package id="WindowsAzure.Storage" version="8.1.1" targetFramework="portable45-net45+win8+wp8+wpa81" />

并尝试与库进行交互，但是只要我做任何事情，应用程序就会以未处理的异常崩溃：

无论我做什么，都可以创建一个新的StorageCredentials对象：

var creds = new StorageCredentials("something", "other");

或新的CloudStorageAccount：

var storageAccount = CloudStorageAccount.Parse(storageConnectionString);

我也一样。我已经通读了github documentation并且没有理由这样做。

有没有人遇到过这个问题并且可以帮助解决这里出错的问题？

修改：

我可以从debu窗口看到它抛出一个NotImplementedException：

Answer 1

...将最新的稳定版本安装到解决方案中的所有项目中....

回复：第3步https://docs.microsoft.com/en-us/azure/storage/storage-xamarin-blob-storage

Azure存储使用本机功能/功能，因此您不仅需要在PCL项目中安装软件包，还需要在每个本机应用程序项目中安装软件包。

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