C# Editor at a conference?

Back in da day, I used to go to VC/VS themed conferences and talk about the debugger. Even though I wasn't a very good speaker, the talks were very well received. Lots of technical content, tips for how to be more productive with the debugger.

When I moved to the C# Editor, I didn't know enough about it to share, but maybe I do now.

I'm looking for ideas about what you'd like to see in a C# Editor talk. 

I could just run through some interesting features and describe their behaviors in detail. We could create some interesting expansions. We could try a small programming exercise, using the various editor tools. We could refactor the starter kit or some other code.

What would you like to see?
