• Interface-Based Programming
  An interface only defines a signature of properties and methods(method name, type of each parameter, type of return value).
  

  1 2 3 4 5 6 7 8 9 10

  interface { int property1 { get; set; } void Method1(); void Method2(); }

A class is used to implement the interface by providing the actual code for those methods.

• Interface Name Form
  Microsoft dictates that all interface names start with the I characters, that they not include underscore character, and that they use Pascal casing when the name contains mutiple words(first letter of each word is uppercase).
