Beginning to work with Windows Store apps

I really hate Windows 8. I think the majority of the applications that have been written for it are complete pieces of shit, for the following reasons:

• The developers who wrote them didn't pay any attention to Microsoft's best practices and they :
• perform poorly
• don't follow UI conventions and are hard to understand as a result
• crash 
• don't always save data properly
• Many are piss-poorly written and adapted by third party developers for first-party systems because those first-parties don't want to write software in a competing ecosystem, and instead want to force users to use their ecosystem, which has their own set of flaws and deficiencies. Case in point: Google. At the time of this writing, there are no native Windows 8 applications put out by Google. There's no native YouTube app for Windows 8 (which there damn well should be), presumably because those fuckers couldn't find a good way to generate advertising revenue in a Windows 8 app. (can't really blame them for that because if I see ads in an app, I immediately delete it from my device without hesitation. I can't stand that shit.)
• Windows 8 is a shit operating system. It was built on the new Modern interface (aka Metro), and initially had piss-poor integration with the desktop paradigm on which all previous incarnations of Windows were based. Add to this the fact that Microsoft didn't give people an easy choice of which paradigm they wanted to use right off the bat, and the fact that in successive iterations like Windows 8.1 they've tacked on hacky additions to make the Metro interface more like the previous desktop interface, you end up with a shitty operating system that's a pain to use; this pain stems from the fact that it's a horrible amalgamation of multiple user interface paradigms. 

As long as Microsoft continues to force their shitty iterations of Windows on the world, I, as a software developer, will be forced to deal with it because of the immense investment most employers have in Microsoft technology. With that in mind, I'm going to start learning Windows 8 applications so that I can make myself more marketable to employers everywhere. I'm going to document my learning here for my usual reasons:

1. So that I have a reference for myself for the future
2. So that others may learn more easily what I have learned.
