windows-phone-7 - 无法从我的 wp7 设备通过 LiveSDK 将 14mb 文件上传到 SkyDrive

Question

上传 5mb 文件不是问题，但是当我尝试上传 14mb 时，我的应用程序已关闭。

fileStream = // get some file as stream from isolated storage

uploadClient = new LiveConnectClient(session);
uploadClient.UploadCompleted += new EventHandler<LiveOperationCompletedEventArgs>(uploadClient_UploadCompleted);

uploadClient.UploadAsync("me/skydrive", "filename", fileStream, OverwriteOption.Overwrite, null);

例外（见屏幕截图）：

A first chance exception of type 'System.NotSupportedException' occurred in System.Windows.dll
Addtional information: NotSupportedException"

当我使用 BackgroundUploadAsync 而不是 UploadAsync 时，文件已传输但大小为 0。

有谁知道这个问题的解决方案？

Answer 1

我找到了解决方案。

!!!IT's IMPORTANT 方法 UploadAsync 应该只从主应用程序线程调用
