LYAH is a phenomenal introductory resource. As companion material I would also recommend the lecture series on C9 by Dr. Erik Meijer, https://channel9.msdn.com/Series/C9-Lectures-Erik-Meijer-Fun....

I second the C9 series. Dr. Erik Meijer does a great job of explaining a lot of concepts you need to understand.
