Earlier quoted context omitted.
Microsoft is the complete opposite of Facebook's "Move fast and break things". And that's a good thing, in a lot of ways. When entire companies (industries?) are dependent on you: slow & steady to get it right is much, much better than moving quickly to integrate the newest technology.
How is Microsoft slow and steady when he just told you they have poor code quality, no docs, etc.
I suggest the OP just fire up the MSDN.
