how to make all property notifiable without ObservableProperty attr

[heartacker]

hi, all guys

how to make all property notifiable. I do not want to add ObservableProperty at all

public AllProperitiesWantToBeNotifiableBydefaultClass: ObservableObject
{
    public Int Age{ get; set;}  // I do not want to add [ObservableProperty]      
}

thanks

[heartacker]

Is there any api to deal with?
thanks

You can use SetProperty, as the docs explain as well 🙂

[Sergio0694]

What you're proposing is just not possible at all in C#, even if we wanted to. Generators cannot modify existing code 🙂

[heartacker]

can this be possible? That is enough at least

[AllPropertiesObservableBydefaut]
public AllProperitiesWantToBeNotifiableBydefaultClass: ObservableObject
{
    public Int Age{ get; set;}  // I do not want to add [ObservableProperty]   
    ...
    ...   
    ...
	so many props
    public Int Name{ get; set;}
    
    [NotObservableProperty]
	public Int IdoWantThis{ get; set;}

    public Int fieldFoo;
	
}

No, this is not possible at all. You have a property there, and you'd like the generator to change it and make it be observable. Generators cannot do this at all: they can only add code. We do want to move to properties in the future, which would get somewhat closer to this, but (1) we need support for that, so not sooner than C# 12 at the earliest, and (2) we'd still keep [ObservableProperty] mandatory over each property. Adding it over a class would make code harder to read, as it would no longer be immediately clear which properties are observable and which ones are not.

and I found this. seem usful https://github.com/Fody/PropertyChanged#overview

Fody.PropertyChanged Works well.
Could you please tell me the difference between the mvvmtoolskits and fody property changed?

Fody.propertychanged can generate the code based on property But according to your description, We are unable to do that

And can do this like fody 's way？thanks
