windows phone 7 script/interpreted available languages?

I found so far javascript and IronRuby is available? My main intention is to get information about avail开发者_运维技巧able way to have run time execution in wp7 application. In other words I want to achieve dynamic behavior without recompiling my app. Wish to listen your input.

As a general rule this isn't available as if true dynamic behaviour was avbailable it would invalidate the purpose of having a certification process before being allowed into the marketplace.

If the logic of the app could be completely changed then the certification process would be pointless.
