Ideal C# talks

We were talking about talks at conferences today, and it got me wondering...what talks would you like to have our team present on at a conference? Or maybe just certain topics?

We used to approach this from a team perspective - learn about the compiler!, learn about the IDE! heres a 1 hour tour of the debugger! I'm wondering if there are specific talks you wish you would rather see from us? Or ways to present information?
