C#属性和ref参数，为什么没有糖

为什么在C#中没有属性和ref参数的语法糖？

csharp
public class Person
{
    private string name;
    public string Name
    {
        get { return name; }
        set { name = value; }
    }
}

csharp
public void Swap(ref int a, ref int b)
{
    int temp = a;
    a = b;
    b = temp;
}
public static void Main()
{
    int x = 10;
    int y = 20;
    Swap(ref x, ref y);
    Console.WriteLine("x: {0}, y: {1}", x, y); // 输出：x: 20, y: 10
}
