Can applications written for windows 8 run on windows phone 8?

Question

As Microsoft said that windows 8 and windows phone 8 share the same code base. If I use visual studio 2012 RC write an application for windows 8. I want to know whether I can install and run the same application on windows phone 8? If the answer is yes we can prepare ourselves for windows phone 8 SDK by learning Visual Studio 2012 RC for windows 8 today!

Answer 1

Right now they haven't announced everything, so this is just my speculation.

I guess that you will not be able deploy the same app (xap file) to WP8 and Windows 8. This by design. Why? Because they are very different systems. Your beautiful, fast and awesome Windows Phone app will suck on Windows 8. There is no silver bullet. It's the same for HTML. You have to create separate mobile version of the web app, otherwise nobody will use it.
