Obviously, I'm not an expert in C#. I would like to simplify this code by using an anonymous handler, or maybe a lambda, not sure. ValueHasChanged is a PropertyChangedCallback used when a dp is changed, it ensures the new object will be monitored for update, so that both changes and updates will be processed using the same code: ProcessN...

So at any one time, there's only 2 active instances...
How much I dig into JavaScript, I find myself asking that much. For example we have window.onresize event handler and if I say: window.onresize = resize; function resize() { console.log("resize event detected!"); } Wouldn't that kill all other functions which is connected to the same event and just log my message in console? If so...
