Redundant ICommand and INotifyPropertyChanged implementations

[davidegiacometti]

ICommand and INotifyPropertyChanged are implemented a lot of time in different mode.
I think where possible would be nice to have a single implementation shared across the WPF projects: maybe in ManagedCommon.

Agreed this would be a good thing to unify.

I think managed common is a wrapper for common. Maybe a new lib would be smarter. .net standard 2.0 since some of these are .net core, others are .net framework 4.7.2 still

Maybe a new lib would be smarter. .net standard 2.0 since some of these are .net core, others are .net framework 4.7.2 still

What about continuing the effort to move to .NET Core and not start a new common lib with the .Net Standard 2.0 limitations?

[crutkas]

I'm seeing FancyZones and Color Picker in here which are on framework. Until those get migrated to .net core, we have to do Standard 2.0.

[enricogior]

FZ Editor will be moved to .NET Core next week.
Having a common implementation for ICommand and INotifyPropertyChanged is a nice thing but is not urgent, if we introduce a new common lib it would be better to not limit it to .Net Standard 2.0.
The project that can start using will adopt it, the project that are still on .Net framework will wait until they are moved to .NET Core.

[crutkas]

i don't think this is urgent

[davidegiacometti]

If we want to use Windows Community Toolkit I think we can close this in favour of #1083

[crutkas]

i'm fine with that but to consolidate / migrate, it is a large effort.

closing in favor of #1083
