Bar Camp Texas: Maybe Bar Campers don't hate Microsoft?

I've heard that a lot of Bar Camps and Bar Campers hate Microsoft, so when I first showed up I whispered that I worked for Microsoft (...right because we all know how quiet I am  :-).  When I walked in the door, I was pretty happy to see some other folks interested in Microsoft technologies and scheduled presentations on them. 

A couple of guys presented on LINQ and Visual Studio 2008.  Here are a few takeaways from the discussion:

LINQ

- Don't pass SQL Connections between methods because you may leave connections open

- var new in csharp, allows you to create more declare variables later and more generic

- var similar to variant in VB but stands for variable not variant
