Looks great @ivanz. I'd love to take this PR. Since this is a PR to a Microsoft repo, let me get the machinery set up to take external PRs. I'll get the ball rolling on that today.

I made some more improvements to handle generic parameters in the method signature and also handle arrays of nullable types:

FWIW, I'm still waiting for the CLA machinery to get set up. It's being worked on though. Once it's ready, would you be willing to sign a Microsoft CLA? (assuming you haven't already)

[ivanz]

Yes no problem whatsoever. I have signed one before.

Hi @ivanz, sorry for the delay! The CLA automation is finally set up. We're currently locked down on the master branch. I'll go ahead and rebase for you against dev.

[DustinCampbell]

OK -- I've rebased against dev and created a new PR - #191. Thanks @ivanz!
