Performance of expression trees

Question

My current understanding is that \'hard coded\' code like this:

public int Add(int x, int y) {return x + y;}

will always perform better tha

Answer 1

C# 6.0 now allows you to do this:

public int Add(int x, int y) => x + y;

instead of:

public int Add(int x, int y) {return x + y;}
