A building list of questions.

This is a running list of questions that I'm having regarding learning to program, the language itself or any methodologies and models that I'm looking at.

• MVC - What is it?  I think I understand what it is.  What I haven't seen is it used in examples to understand it's practice.  Why do all explanations of this leave out examples?  I have a theory about this.
• MVVM - Related to MVC, what is it? How do you use it? Is it applicable to what I'm trying to do?
• XAML - Do I need to learn it to do interfaces in Windows?  Can I just get away with what Visual Studio enables me to do?  I have a feeling the answer to this is yes, learn it.
• What are the key parts of C# that I need to learn to make functional applications in either WP7 or Mono for Android?  How deep do I have to go in learning the language?  So far I have covered:
• Conditionals
• Data types
• Object oriented practices
• encapsulation
• inheritance
• namespaces, classes and methods
• General language syntax
• What I haven't learned about C# yet
• interfaces
• enums and lists
• general I/O
• exceptions
• anything related to controls or graphics

I'll update this list so I can keep track of my progress and thoughts.  Hopefully I'll find good explanations to most of these but as with anything I read there are often more questions than answers, and that's great!
