Port25
Port25 is the website of the Open-Source Software Lab at Microsoft.
They seem to be quite busy. . .
And the DO offer code for download 
! They distribute their code under licenses which they call ‘Shared Source Licenses‘ . There’s a nice summary on Shared Source Licenses at the Wikipedia:
http://en.wikipedia.org/wiki/Shared_source .
Or, you could read the licenses themselves also of-course 
.
Port25 also contains info on how to make some open-source tools work along with Microsoft’s tools, Straight from the horse’s mouth. A good to have resource, of course.
