Declarations vs definitions

Question

In C# how does a declaration differ from a definition, i.e.:

1. A class declaration vs a class definition
2. A variable declaration vs definition
3. A met

Answer 1

Answers to original questions 1, 2, 3: no difference in C#

However might be worth mentioning those terms in regards to methods:

• Declaration is place in Interface where we just "declare" the signature of the method
• Definition is the actual place where we "define" the actual implementation of the declared previously method. (same as "implementation")
