    "Html": "<p>Ahh, Well then it seems like it is not a problem in DotNetZip.</p>\r\n<p>The most common problem when saving to a MemoryStream is that people forget to call .Seek() on the memory stream, after writing it, and before reading it. There were 2 people this week that had this problem.&nbsp; Maybe that's your problem here. If I'm right, you'd need to call <strong>ms.Seek(0, SeekOrigin.Begin)</strong> before transmitting ms over the WCF response.</p>\r\n<p>Good luck!</p>",
