refactor: use a tuple to initialize properties in the constructor

[aloisdg]

That is just a syntactic sugar:

public Point(int x, int y, int z)
{
    X = x;
    Y = y;
    Z = z;
}

can be written as:

public Point(int x, int y, int z) => (X, Y, Z) = (x, y, z);

The compilation result are the same.
