Just kidding. I did hear the words "strongly typed" used repeatedly.
But it's interesting to see the productivity people had with the older VB (where you did not have to worry about data types) combined with the robustness of C# (where you do have to worry about data types) -- but now it's the compiler that does the worrying for you.
That in itself is going to be a huge win. All those null vs. dbnull vs. empty string bugs... GONE.
The fact that it's universal... wow. Now maybe when I code against Outlook I can stop messing with collections and enumerators and retrieve the items I want in 5 lines of code instead of 50... using the same syntax I use to query databases...
