I have a project that builds and runs on Windows Desktop and Phone. I can also deploy it to the phone when it is connected.

However, I cannot for the life of me figure out how to create the package (.xap or the new .appx) for the Store. Every time I build with whatever kit, it always creates a .exe file.

I tried converting the project to a visual studio project. Once I opened the project in VC, another issue came up. It didn't detect the project as a Store project so it wouldn't give me the "Build/Store" menu that is used to create the final package.

What do I do? I have to say that I cannot understand anything that goes on in the documentation. It is almost exclusively command-line stuff. Most of it has no build up (i.e. go here, then here, because xyz); instead it is just "enter this command". Nonetheless there is nothing about the final xap or appx package creation.

I have a similar issue with Android where it builds successfully but then says error in building with no explanation. But first, I would really like to understand how to do this packaging business. Sorry if I sound horrible but this is months of fruitless searching, reading and trying things that don't work.
