Recently, I have been running into some problems with XML Serialization in VB.Net. I suppose this would apply to C# as well, but I don't do that. Anyway, at work, we've been trying to get ourselves integrated with Amazon.com. We're going to be selling our wares there. It's very exciting but VERY frustrating too. Amazon requires merchants to send up XML documents (feeds) to describe things like products, prices, inventory levels, etc...
