Xamarin.Forms 5.0 - NuGet Packages Not Resolving

Question

Good Evening,

Hello,

Welcome to Microsoft Q&A!

I test on macOS Catalina(10.15.7) everything works fine , I'm able to update package Xamarin.Forms to 5.x.

However macOS 11.1 is released in Big Sur , I would suggest your raise the issue here though official docs mentioned Visual studio for mac 8.8 has supported Big Sur .

In addition ,you can try to test with a new blank project to see if error persists , and try to install VS for mac 8.9 .

Thank you.
