Here are the slides and here is the code for my Using Design Patterns in .NET presentation.
My talk, Exchange.NET: Accessing Microsoft Exchange data using the WebDAV protocol with .NET, seemed to go over pretty well today. Thank you to all who showed up for the presentation.
For the people who went to my presentation and download this code, if you find bugs in it, please let me know and I will fix them. Once I fix the bugs, I will send you the new code. Actually, what would be really cool is if you post them as comments to this blog post :)
I didn't get time to really go over the details of the WebDavXmlHelper class, but it basically trivializes parsing the XML WebDAV responses from Exchange. Like I said in the talk, if nothing else, WebDavCommand and WebDavXmlHelper are worth having in your toolbox.
