I'm working on Mac OS desktop app with Xamarin.Mac.
Every time after I open and edit main.storyboard in XCode interface Builder, Project's target framework changes to "Xamarin.Mac Modern". Because of it I have to change it to "Xamarin.Mac Full" to build the project. Why this happens? Is this a bug?
** Error Message **
I get following Error message when I try to run the app if I don't change target framework from "Xamarin.Mac Modern"
System.io.FileNotFoundException thrown. Could not load the file 'System.Net.Http'.
** My Environment **
Mac OS Catalina 10.15.6
Visual Studio for Mac 8.7.5
Xcode 11.7

Same issue happening for me. Looks like a bug, but it reproducing not for all projects (for clean, just created solution it almost always woks fine), so I still can't build minimal reproducible sample to submit bug report.
Anyway, I will be happy to know about any additional details and fixes/workarounds.
** My Environment **
Mac OS Catalina 10.15.7
Visual Studio for Mac 8.7.8 build 4
Xcode 12.0.1

I was able to reproduce the issue on the just created project and reported the issue on GitHub. So, for reference for those who may find this topic in Google: https://github.com/xamarin/xamarin-macios/issues/10010
