@apardoe, one question: where will the compilation to machine instruction happen? From some comments in this thread, it seems that it will happen at app store server and not at developer's box. If that is the case then why will I need anything to do any settings in VS for building projects?

[apardoe-MSFT]

@rajeevk, we could compile from MSIL and not tell the developer. But you probably appreciate the chance to test out the app on your own the way your user will run it. After all, you'll want to profile it or maybe find that last on-device, optimized-only bug...

What about stuff like Il.Emit and Expression<T>.Compile

[apardoe-MSFT]

Reflection.Emit isn't allowed in the Windows Store profile so we haven't handled it in this go-around. Expression compile is supported and handled properly.
