If I would start to focus on the .NET platform and be self-employed, then I probably would like to have some Windows 7, Windows Server 2008, Visual Studio 2010 licenses just for the development environment and for testing, and then a few licenses for the production environment (a Windows Server 2008 Web) and added to that upgrades when new versions is available. This will end up in a quite big amount of money.
Is there any kind of bundle discount that I can get from Microsoft in such a case? And what is the requirement to be able to get that discount?
