On the topic of WPF apps in .NET core:

Can anyone who has successfully migrated WPF apps to .NET core, in production, chime in on what was the experience like? Any major pitfalls or pros/cons to consider?

I have a prospective client, running a WPF app in a soon to be deprecated windows embedded machine. They have a lot of domain knowledge in the app so are unwilling to re-write or port.

I was thinking if it is feasible at all to migrate this WPF app to .NET core and then migrating the target to a higher longevity Linux machine.
