How do I learn? Or rather what?

KK here's what's up:
I want to learn .NET development. I have limited experience from C++ and have been messing about with C# lately, making server/client apps, connecting to MySQL etc. Good times.

But I'm lost as to what the hell I'm supposed to do now. What am I supposed to learn? I'll be slowly grinding out the uhm, standard C# "library" :), but what do I do in the meantime? I'm perhaps leaving this too open, I guess I'm basically asking what I specifically should focus on to become a good programmer ready to go into a career as a programmer without a school diploma.

Also how does programming go down in the business world? Let's say for a .NET application with 10 or so programmers, how is the project managed, are there any good online documents on this?

Thanks in advance!

.NET is good for getting a job.  So is Java.  /prog/ is not about grinding away at enterprise programming.  If you want to get a job, learn .NET or Java and program, monkey boy.  If you want to hang out on /prog/, read your SICP.

Ignore the jokers who tell you C# is not portable.  Mono/C# on Linux / OS X is damn fine, and you can write C# for Android / iPhone too.  (And the thing about compiling to native code for a speed boost?  Hah!  >>9 doesn't know what he's talking about, native code only speeds up launch times, and the Java->native code compilers are terrible.)
