Collection-Type Dependency Properties lacks working example

[SetTrend]

The below mentioned documentation page only provides examples for non-working code. However, It lacks the most important part: A working example of how to apply a FreezableCollection<T>.

How is a DependencyProperty created using FreezableCollection<T>?

Please add a working example of how to apply FreezableCollection<T>.

Hey there! I'll add this into the planning work for the .NET 5/6 stuff. We're not really updating .NET Framework content with new stuff right now.

Thanks, Andy!

Have a nice day,

@dotnet/wpf-developers Do any of you have an example of where FreezableCollection makes sense? I would love to see "Hey you used List, look at how its broken with databinding. Here is the code converted to FreezableCollection and now it works"

We added a small example of creating a freezable collection dependency property. We added some description to it to hopefully explain some of the ideas around it. The API article for it though, in the remarks, has a more thorough explanation. I don't think we'll add anything further on this unless the WPF devs come back with some more info. I'll close this for now.
