[Q] Is it possible to use MS.Internal somehow in a normal app?

---

Is it possible to somehow use classes from the MS.Internal namespace, things like MS.Internal.TextBoxView which is the type of a sub-object of the ContentControl of a textbox?

I mean use them in a "normal" app on a locked end-user phone, and getting away with it as far as certification is concerned so it can appear normally in the Marketplace?

The Visual Studio debugger is able to display information about such objects somehow, that's where I got the knowledge of the existence of this TextBoxView class in the first place, but of course that does not mean that a normal app can do likewise.

Googling for "WP7 reflection" showed me hits in other places like StackOverflow with info that probably this will just run into security exceptions anyway, because MS does not want devs to use "undocumented APIs", but I am curious whether somebody here has tried to "hack" this and can report first-hand.

I highly doubt.. more towards no for this. Microsoft pretty much will deny anything in the low level APIs from being accepted in the Marketplace. A way to check this is to use the Marketplace Test Kit in VS 2010 (Project -> Open Marketplace Test Kit). It will tell you if something you're using will fail as it does the same type of quick test that happens when you upload a XAP for submission.
