Microsoft officials Monday confirmed at the company's MIX 10 developers event in Las Vegas that native applications will not be allowed on Windows Phone 7 devices. Only applications running in the Silverlight runtime environment or games in the XNA Game Studio runtime will be allowed.

That was the answer by Todd Brix, Senior Director for Mobile Platform Services Product Management, to a question from UK-based technology journalist Tim Anderson.

Brix confirmed that Windows Phone 7, the user interface overlay atop the Windows Embedded CE 6.0 Release 3 kernel, runs only interpreted or managed code through the two runtime environments provided by Silverlight and XNA.
