As some mentioned this is a new feature brought first to C# 6, they extended its usage in C# 7.0 to use it with getters and setters, you can also use the expression bodied syntax with methods like this:
static bool TheUgly(int a, int b)
{
if (a > b)
return true;
else
return false;
}
static bool TheNormal(int a, int b)
{
return a > b;
}
static bool TheShort(int a, int b) => a > b; //beautiful, isn't it?
