Hello,

Welcome to our Microsoft Q&A platform!

You can try the following steps:

1.Please try to delete bin and obj folders, then restart VS and clean Solution > Rebuild Solution .

2.If the problem persist, make sure you have checked Tools->Nuget PM ->Nuget Package Manager settings -> Allow NuGet to download missing packages

Best Regards,

Jessie Zhang

In general, we could find some relative error logs in the output window if there is any problems. You can try to Repair your Visual Studio. For more, check document: https://learn.microsoft.com/en-us/visualstudio/install/repair-visual-studio?view=vs-2019 .

In addition, could you please post a basic demo to github or onedriver so that we can test on our side?

I tested on my visual studio, it works properly. And the Target Android Version in my visual studio is android 11.0. You can try to perform a thorough uninstall for Xamarin for Visual Studio. For more detaisl, you can check: https://learn.microsoft.com/en-us/xamarin/cross-platform/troubleshooting/questions/uninstall-xamarin-vs .
