Windows 8 will be capable of running on different processors, how will this impact a developer's choice of development technologies?

Question

Thanks.

Answer 1

If the application in question is a Metro application and you do not use anything really special, you would not care. You will just recompile the same code for each CPU.

If it is a desktop application, then the impact is not known. Microsoft is unpleasantly quite about desktop application.

Answer 2

So, is the onus on the developer to remember to compile for different architectures and submit each build to the app store or will there be an option to build one fat binary and let some 'magic' in the store deploy the right version for the app buyer?

Answer 3

You should test each architecture before deploying as some bugs might be "working" on only specific architecture, for example bugs connected with serialization or in calling native functions etc. You should also sign binaries using your code signing certificate which is operation which should not be processed by anyone else.
