The size improvement is going to be really interesting to me. Currently I have to choose between shipping small Framework 4.8 apps, or the whole kitchen sink with .net 6 even for a trivial wpf+ef app. Trimming and readytorun did not produce significant improvements unfortunately.

I haven't done much desktop/UI work but don't the small Framework 4.8 apps rely on the proverbial kitchen sink being pre-installed on a user's machine? Because afaik this is also possible with newer .NET [Core] applications, and indeed is the default. You just also have the option to publish and distribute a larger bundle which includes the runtime + required libraries.

Correct. The difference is that 4.7/4.8 came preinstalled on win10 for years now. It can be uninstalled so you can't really rely on it, but... 99% of the time it works. If not, you tell the customer to install it.

The UI frameworks are hopelessly interlinked. I can't even get it to trim out WPF from an all-WinForms app. I don't have any hope that this will improve substantially for desktop apps; I'm sorta just happy they're still supporting our desktop UI frameworks at all.

WPF and Web Forms are almost dead. Now MAUI is taking over. I hope this one won't be dead, too, in a few years.

I don't get why people are repeating that. WPF is not dead, it's fully supported and the project has a future roadmap. (https://github.com/dotnet/wpf/blob/main/roadmap.md) MAUI is not taking over, it's not even released yet. We only just got a release candidate 3 this month. Looking at local job postings, WPF had hundreds of hits, while MAUI has... 3 "xamarin or maui" mentions.

Would you give a chance try trimming WinForms on .Net 7? I do expect it to be slightly better now

I also had no luck with trimming.
