INotifyPropertyChanged and Auto-Properties

Question

Is there a way to use INotifyPropertyChanged with auto-properties? Maybe an attribute or something other, not obvious to me.

public string Demo{     get;set; } 

For me, auto-properties would be an extremely practicall thing, but almost always, I have to raise the PropertyChanged-event if the property value has been changed and without a mechanism to do this, auto-properties are useless for me.

Answer 1

In .NET 4.5 and higher it can be made somewhat shorter:

private int unitsInStock; public int UnitsInStock {     get { return unitsInStock; }     set { SetProperty(ref unitsInStock, value);} } 

Answer 2

It's something you would have to code yourself. The closest you could get would be something like this implementation on Code Project that uses a custom attribute and aspect orientated methods to give this syntax:

[NotifyPropertyChanged]  public class AutoWiredSource {     public double MyProperty { get; set; }  }

Someone once proposed on Microsoft Connect a change to the C# specification implement this:

class Person : INotifyPropertyChanged {     // "notify" is a context keyword, same as "get" and "set"     public string Name { get; set; notify; } } 

But the proposal has been now closed.
