I'm wondering how you'd recommend designin a class, given the fact that XNA Framework uses Struct all over the place?

For example, a spite class, which may require a Vector2 and a Rectangle (both defined as Struct) to be accessed outside of the class.

The issue come in when you try to write code like this:

class Item 
{
    public Vetor2 Position {get; set;}
    public Item() { Position = new Vector2(5,5); }
}

Item i = new Item();
i.Positon.X = 20; // fails with error 'Cannot modify the return value of Item because it is not a variable.'

// you must write code like this
var pos = i.Position;
pos.X++;
i.Position = pos;

The second option compiles and works, but it is just butt ugly. Is there a better way?
