I have a solution with a bunch of Xamarin.Forms cross-platform apps. I'm in the middle of a refactoring where I'm migrating things to Nuget PackageReferences. While doing so I encountered a few problems with portable app projects that referenced Xamarin.Forms, so I decided to uninstall the package from these apps and re-install it, then everything worked perfectly. While doing so, however, I realized that if I didn't reinstall Xamarin.Forms on the portable app package, things would still compile and work.

Can someone please explain to me how it's possible that a C# project that contains Xamarin.Forms code in it doesn't need to have a reference to the Xamarin.Forms package to compile? And does this have to do with Nuget PackageReferences? enter image description here

Syncfusion.Xamarin.SfChart has a Xamarin.Forms dependency and thus it is auto-added to your project.

Dependencies

  • Syncfusion.Xamarin.Core (>= 18.2.0.54)
  • Xamarin.Forms (>= 3.6.0.344457)

as it is well explained before another package has a reference to Xamarin.Forms, but... that's my addition to the response. I see in your code that you have a using Xamarin.Forms; statement, you are adding it as an indirect reference and then you are adding it to that part of code in a using statement that is not erroring. If that should not be added, then it will show with an underlying red mark, then in an error.
