Journey to robust web services: apparently we shouldn't use 'using'

I recently stumbled across an article stating why we shouldn't use the 'using' keyword with WCF services, and I found it rather interesting. I'd have to re-read it, and re-evaluate it, before I use it but you can read the blog post on the original site.

Composing XML in C# 2.0 or later

When testing some custom XML serialization I was writing for a project, I ran across a quirk of the XmlWriter created by XmlWriter#Create() : The writer that gets produced by this method doesn't actually write out XML to whatever stream or file you've given it in the Create method until Close() is called on the generated writer. This means that if you've been using the XmlWriter along with a using() statement, you're fine, but if you haven't been using it, as I have in the unit tests I've been trying to write, you're going to get some unexpected results. Something to pay attention to.
