On my last post about the news announced today by Somasegar for Visual Studio and Windows Vista "life together", I've concluded with an esclamation: wonderful!
The "wonderful" word was leaved there with a bit of sarcasm, but the feedback given me by my friend Lorenzo Barbieri (thanks geniodelmale 
)has revealed me that its sense was not totally understood, so here is my real reply.
I think that on the Somasegar's post there are good things and bad things.
On the good things category, I add the fact that Windows Vista will ship with the .NET Framework 3.0 pre-installed and that the support for .NET 1.1 and .NET 2.0 application is guaranteed. Having the last Framework released as native on the OS is a great thing, no need to update systems (we spend lots of time on our everyday work to update customer's systems with the .NET Framework) and an ensure that .NET will be a core part of the system.
On the bad things there's the news that they will not support Visual Studio .NET 2002 or Visual Studio .NET 2003 as development environments on Windows Vista. 
When I've see this news today I was a bit worried and my thinks was totally on my work and my customer (or the major part of them). Actually I try to build all the new applications with the new .NET 2.0 platform, but I've a lot (a big number) of applications that runs on .NET 1.1. My first think was this: I've to order to my boss a new desk because I'll have to setup a machine with Windows XP and one with Windows Vista... 
I don't know why this decision, but seeing that VS2003 is not supported on Vista will be a real problem for many of us and a clear sign that Windows XP will survive a lot after Vista: despite all the spots for Vista, XP will be the number 1 platform for a lot of time I think. We need to give support to customers and .NET 1.1 is a platform too much used today.
But my worried thinks was also for another part of my work, the Microsoft Dynamics product family.
Microsoft Dynamics NAV 4.x has not a native support on Vista (although I've seen some tricks in order to run it with the new OS) and we've to wait for the 5.0 release (half 2007) in oder to have a full support for Vista. But the 5.0 release will be a big big improvement on the architecture and the environment, so how many customers will decide to migrate to it? Not too much or, at least, not too much in a short time. So? They will remain with their Windows XP clients (and we've customers with a very large number of clients).
What about Microsoft Dynamics CRM 3.0? The last Microsoft's CRM system supports .NET 1.1, so Visual Studio 2003 is the natural environment for development. Will be possible to work with Dynamics CRM on Vista? I think the answer is yes for the client part, but if you want to have a development environment, you need a Windows XP machine.
Why inside Microsoft noone has done these considerations? Was so difficult to not drop the support for Visual Studio 2003?
Maybe someone a day will give us an explanation, for the moment we'll wait for Vista (too much exciting) but we'll refresh our Windows XP machines: dear XP, a long period of work is waiting for you!
