From what I've heard, DataSet was not included in Windows Store Apps because it's considered to heavy. The Microsoft Object Relational Mapper (ORM) is Microsoft Entity Framework.
When I started, I was under the impression that porting from Windows 7 to a Windows Store Application would be easy. I ended up rewriting the vast majority of my Windows 7 code. Your milage may vary, depending on what you're doing.
I can live with the idea that we're changing paradigms. What's hard for me is the documentation from Microsoft, which at times is horrible. This creates a void that people who write articles and create podcasts try to fill. While I think the vast majority
of those folks have good intensions, they are sometimes dead wrong. You can end up committing a lot of time to half-baked ideas that won't pass the Windows App Store Certification tests.
I hate to say the following because I invested a lot of time learning to program in Windows 8 Store Apps - still, I don't think Windows 8 has a bright future. Users cannot figure out how to do basic things, and literally end up taking their device back
to the store. Programmers look up API documentation to find no code sample, and a description that just parrots the name. If Microsoft doesn't fix these problems in the eyes of their customers, they will eventually go the way of Pontiac and Oldsmobile, and
that would be bad for everybody in my opinion.
