I opened an old abandoned project on my computer(about 2-3 years old) on Visual Studio. I debugged the application and seemed to be in a working condition except for a few small problems(related to the code)
So I updated my packages:
And now I've over 62 errors and multiple problems in my code which were working when I first developed it and when I'd just opened it for the first time in an older Visual Studio version, now I'd assume that some things might have changed and I'm willing to look into that. But I'm overwhelmed with 62 errors for a project that I'm not well-versed with anymore. I've no idea which reference library I'm missing.

This is the documentation I'd referred to while I'd made this: https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/map-pin However this article has not been updated ever since I referred to it, so I'm unable to find out any obvious problems.
Had the same issues. I looked at the csproject file in a editor and saw that there was a package reference added to Xamarin.Forms.Platform.IOS to my Android Project.
Removed that and it worked fine :)
