Hi Alex,
You're actually correct in this.
I submitted a large number of sessions this year for DevCon, a mix of plain VFP, VFP with .NET and a couple of pure .NET sessions. Advisor picked the 2 most .NET centric sessions this year which was a little surprising to me, especially since the sessions weren't picked in previous years.
I'm the one doing the 'Migrating a Fox Web app to ASP.NET' session and I think that it indeed an interesting topic because it points out the process and the end result which is a mixed bag. I personally think that this is interesting for people who are in the process of moving to .NET as well as people who have not looked at .NET before but are interested of why you might even consider doing it. This is actually a way to see how something is done in Fox and how it's done in .NET and how the end result compares.
