The language shortcut

public string Code
{
    get;
    set;
}

saves a bit of typing when defining trivial properties in C#.

However, I find myself writing highly repetitive, not-quite-as-trivial property code that still follows a clear pattern e.g.

public string Code
{
    get { return code; }
    set 
    {
        if (code != value)
        {
            code = value; 
            NotifyPropertyChanged("Code");
        }
    }
}

I can certainly define a Visual Studio snippet to reduce typing. However, if I need to add something to my pattern, I have to go back and change quite a bit of existing code.

Is there a more elegant approach? Is a snippet the best way to go?
