LOL - I was considering saying 'wow Cold Fusion is STILL around???' - I never latched on to Macromedia, and kinda went right to MySQL on the web. Even though I have a huge investment in Adobe Suite products, I will have to admit I had to do a Google on CF9 - that is how far out of my brain stream it was.
I'm NOT an expert on things dot.net (although I used to do SQL Server - but I used a proprietary development system that was built over VS, and I never saw the guts - that stuff I did is all now part of MS itself[Dynamics]). I think Hackattack or some of the others might know better. And you should think about MS changing the development paradigm again for Windows 8.
I'm a database, info-structure and architecture guy, and I mostly work with 'frameworks'.
I hope you did post a couple questions over there, because I'm as curious as you are. I do think you are being realistic on 'sunsetting Cold Fusion' and looking for newer, perhaps more nimble (note - no use of the well-worn-word agile) environments. A lot of your choice should be dictated by the requirements of your target applications - might well be time for 'Azure Tides'. Java is certainly a choice for app-building, and has a pretty good head of steam right now.
