You may have noticed my “I'll be there” picture.. I'll be there--isn't that like a really bad Michael Bolton song or something of that ilk?
Anywhoo, I'll be at Tech-Ed this year talking about VSTO 2.0 mainly, but I'm sure I can help you out if you have questions about VSTO 1.0.
The first talk I'll be giving is Dev 367 which is an overview of VSTO 2.0. There'll be lots of demos and not many slides--you should have a good sense of what you can do with VSTO 2.0 by the end of this talk.
Also, I'm giving another session you can sign up for with the very descriptive and apparently case-sensitive title TECDEV17. This will be about security and deployment features of VSTO 2.0 although most of what I'll talk about in this talk will apply to VSTO 1.0 as well.
Finally, I'll be on the floor to answer questions, or at least point you in the right direction--so look me up.
Hope I gave you some additional reasons to get your boss to send you out to this conference.
