CRM 4.0 SDK System Requirements

Hello.

Im about to develop a customer portal in ASP.NET MVC using the Dynamics CRM 4.0 SDK.

I have been searching the internet for the system requirements and found:

"Supported operating systems: Windows Server 2003

Microsoft Visual Studio 2005 or Visual Studio 2008" -Microsoft article, 11/2/2010

So, I wonder: Since Windows Server 2008 was the latest OS at the time when the article was written, is the SDK "locked" to Windows server 2003 (and the versions of Visual Studio listed)?

Or will I be able to use the 4.0 SDK in any OS, eg. WS 2008 or W7 with VS 2010 or 2012?

Thanks in advance!
