If it's a good article? No, not at all. I've done it in the past.

That being said, I do always prefer an official MS reference. But if there isn't one, a third-party reference that is solid enough (read: based on other MS material, or equipped with enough code samples to prove that the statements are true) will do just fine.

I don't know your article, but I do know you - and that's enough for me to assume that your article will meet the bar. Easily!
