What are Good Things to Know in a C# Interview?

What are Good Things to Know in a C# Interview?

Off the top of my head, I have come up with this list:

• SOLID mythodology.
• Dependency Injection
• Levels of Try, Catch, throw, and finally statements and how they work
• The tenants of Object Oriented Programming such as polymorphism, enacpsulation, etc.
• Unit Testing (are interfaces used somehow)
• The difference between an abstract class and interface
• garbage collection and when to override or overload it
• difference between override or overload
• Is there inheritance in C# ?
• What is an interface used for?

I am posting this here to see of anyone can add to this list. I am asking about general topics, not specific interview questions.
