Question

Is there any official In App Purchase for windows phone same like iPhone (which connects to iTunes).

Here is the nice explanation about In App Purchase

In-app purchase (IAP) means buying more content for the app through
Marketplace while in the app. Another name often used for them is
micro-transactions for the smaller purchases. Buying a new costume
for your character. You need several thousand gold coins to get that
pet cat in the game you are playing. You could play the game and
grind away killing monsters over several hours and earn the XP to get
the cat, or you could pay $2 now via in-app purchase and have the cat
straight away.

Thanks

I believe there is no such possibilities at the moment on the Windows Phone 7 platform. Also the next version of WP7 OS codename Mango will not have the In-App purchase feature. Here is the comment from Todd Brix

@BNID, @Justin Pitta; In app commerce has been on the short list of
features we’d like to enable, but unfortunately it did not make the
cut for Mango.
