Question

我有一个可移植的类库（支持.NET4.03，Silverlight 5，WinPhone 8和WinStore的配置文件147），它使用HttpClient进行HTTP调用。除了Silverlight 5之外，该库在所有平台上都能正常工作。

当从SL5应用程序使用库时，尝试使用GET谓词调用SendAsync方法会导致NotImplementedException：

{System.NotImplementedException：未实现方法或操作。在System.Net.Browser.ClientHttpWebRequest.set_AllowAutoRedirect（布尔值）}

我没有调用这样的方法（它暴露在HttpClientHandler类上）。我设置了几个HTTP标头，但它们似乎与此问题无关。

这里有什么不妥？

UPDATE 以下是异常堆栈跟踪：

从Silverlight应用程序调用时，PCL中的HttpClient会抛出NotImplementedException
