Microsoft has a webpage titled “Deploying Microsoft .NET Framework Version 3.0″ that has oodles of info about the new product that was previously known as WinFX.

Here’s what I found really exciting:

Because .NET Framework 3.0 is an additive release and uses the core run-time components from .NET Framework 2.0, it is completely backward compatible with the earlier version. Your existing .NET Framework 2.0 based-applications will continue to run without any modifications and you can safely continue your investments using the technologies that shipped with .NET Framework 2.0.

In addition:

The .NET Framework 3.0 is installed by default on Microsoft Windows Vista.

I’m assuming this means that .NET Framework 2.0 applications will be Vista-compatible. Cool!
