Ask HN: Are you developing anything for Windows mobile phone 7?

I think referring to the technology as "Windows Phone 7" or "WP7" will probably generate better responses.

And I have one in the works, yes.

No. I've heard good things about it though...

Nope. We've tried a few in the past and they've just done NOTHING so we're not going back. We have much more success on android and apple even with the increased competition.

I'm on some little project for WP7 too. I think that more developers will adopt WP7 when they see it has a clear future. At the moment it's a bit cloudy, we still don't know if it will continue growing or not.

Anyways, being the first on WP7 is risky but can be very profitable. Kik Messenger grew a lot thanks to their WP7 app (the article is in TC, can't search for it now). There are few apps so there is less competition and you can get a lot of new users.

What language/SDKs one has to use in order to write windows 7 apps? Is the overall experience different from iOS/Android app developing? How do one test the apps?
