Learning for real employment

Question

I have a 20 year career in another programming platform.  I've started to learn C#, .net and WPF with C#.  There is so much out there that I don't know where to concentrate.  I understand some basics.  I helped on a WPF project at work so that is how I got started with WPF but I want to know how to write .net applications from start to finish.  I start to write something and then someone says thats not the correct way to do it...  I want to learn C# and WPF the correct way as it would be used in the real business world.  Where do I start?  What else is important to learn?   I have written database programs in my old language so I'd like to start with desktop apps in C# and WPF since i'm familiar with that concept.
