which is the proper way to code getters and setter on c#

Question

public int getX(){
return x;
}

Or

public int X {set => x = value; get => return x;}

Answer 1

it's a matter of choice it doesn't really matter.
the second example is fully introduced in C# 7 ( it was limited in C# 6)
form Microsoft docs.
" Expression body definitions let you provide a member's implementation in a very concise, readable form."
so it's about readability, I guess.

Answer 2

The second one. The first one is just a method it does not make X a property.

Answer 3

public string Title{get;set;}
