I am using this in Unity by the way, Which I dont think uses the most up-to-date version of C#
It should be available in C# 8
Not sure about the sealed part

Default implementations in interfaces With last week’s posts Announcing .NET Core 3.0 Preview 5 and Visual Studio 2019 version 16.1 Preview 3, the last major feature of C# 8.0 is now available in preview. A big impediment to software evolution has been the fact that you couldn’t add new members to a public interface.
just following what is written here doesnt seem to work, just using public void for the child class makes the compiler tell me that I need to use the new keyword
If you don't put the one that has the default implementation onto the class that is implementing the interface, does it complain that there is no implementation?
ah, I see. Thats a bit confusing
I dont need to use new, sealed or override at all, I just needed to use ICommand.Process in the child interface to override it
The learn page that is linked at the end of the article shows a pattern to extend/override the default implementation
ok well thanks for the help there
I will have a look at that
