No Qt on windows phones, although Nokia's site still says:

http://developer.qt.nokia.com/faq/answer/is_qt_compatible_wi...

"Is Qt compatible with .NET?

Yes. You can use Qt to create .NET-compatible applications. For details on how to do this, please refer to Using Qt objects in Microsoft .NET in the documentation at http://qt.nokia.com/doc/activeqt.html.

Apparently they integrate Qt with .NET via COM, which AFAIR is not available on Windows phones.

qt. laughes microsoft will send it toward the round file of patents. have you tried silverlight in linux? its meth. not good for your system.

How can Microsoft send a Nokia asset to the round file of patents? They didn't buy Nokia. Also, the performance of Moonlight says nothing about Windows Phone.
