Download large file from Skydrive to Windows Phone 7

Am having some trouble with the SkyDrive download process and hoping you can help me.

Following the standard SkyDrive API & examples, I've set up a page that browses the SkyDrive folder structure, lets User click on a file, prompt to download, and it all works correctly.

Where I'm having trouble is when the file downloaded is large, I get the OutOfMemoryException thrown at around the 100Mb mark.

Dennis speaks on this problem here http://dotnet.dzone.com/articles/2-things-you-should-consider but it relates to a direct URL download, not via the SkyDrive architecture.

I've tried extracting the URL from SkyDrive and doing the direct download that way but haven't had any success.

Here is the code I'm using - the "item" object is of type SkyDriveItem, having iterated through a folders content and selected this file.

LiveConnectClient downloadClient = new LiveConnectClient(App.Session);
                    try
                    {
                        downloadClient.DownloadCompleted += new EventHandler<LiveDownloadCompletedEventArgs>(downloadClient_DownloadCompleted);
                        downloadClient.DownloadProgressChanged += new EventHandler<LiveDownloadProgressChangedEventArgs>(downloadClient_DownloadProgressChanged);
                        downloadClient.DownloadAsync(item.ID + "/content", item);

This will work fine when the file isn't too large, but as mentioned, select a big file (>100Mb) and it dies with the OutOfMemory exception.

Any pointers?

Thanks in advance

Resolved - While I was never able to use the downloadClient.DownloadAsync() method to download large files, playing with the downloadClient.getAsync() and using the Pre-Authenticated URL via a regular Stream downloader does the trick.
