I am trying to migrate the Xamarin.Mac, Xamarin.iOS and Xamarin.Android native to .Net iOS, Android and MacOS by using below tools

upgrade-assistant upgrade <Path to csproj to upgrade>

However I’m facing the issue while doing In-Place project upgrade or side-by-side project upgrade. the error message is “There are no target frameworks found to which your project could be upgraded.” Find the below error image.

How to solve the this issue in Mac. Any idea ?

I have verified the dotnet 6, 7 and 8 version but it same result.
