The addin is already blogged about so I won't go into any detail. To the right of each "download link" is a link that will show your personal license key for the selected product (keep it private).

Choose a Visual Studio 2010 Professional download from the list and install it. On msdn you will see a large list of available downloads on your msdn downloads page. The big button actually signs you up to the microsoft developer network (msdn). Once you have signed up you will see a big button allowing you sign up for downloads. To take advantage of the offer you will need to sign up for the free Microsoft WebSiteSpark program. This appears to open the door to Visual Studio to just about everyone in the arduino community. The extended Microsoft offer provides immediate download and 3 year license for a huge range of products such as Visual Studio 2010 Professional.

One group being any individual who is thinking about becoming a web developer. 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.
