Overview of reference types in C#

Classes are reference types in C#, but there are others as well

Reference types
- Classes
  - Strings
  - Arrays
- Interfaces
  - Similar to classes. Contain no data. Have only signatures of methods
- Delegates
  - Delegate objects can contain one or more methods
  - Used when we deal with methods as data
