It was already possible for students and teachers to obtain a free version of Visual Studio 2010 Professional but now this Microsoft offer has been extended to a number of other groups. One group being any individual who is thinking about becoming a web developer.
The extended Microsoft offer provides immediate download and 3 year license for a huge range of products such as Visual Studio 2010 Professional. This appears to open the door to Visual Studio to just about everyone in the arduino community.
To take advantage of the offer you will need to sign up for the free Microsoft WebSiteSpark program. Once you have signed up you will see a big button allowing you sign up for downloads. The big button actually signs you up to the microsoft developer network (msdn).
