ld: framework not found System in Visual Studio 17.6 XCode 14.3

I have a .net Maui Blazor project that has project reference to a .Net Maui dll. Everything works fine when I compile it as "Windows Machine" But when I try to compile it as any iOS project ig get this error:

2>C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk\16.4.7054\targets\Xamarin.Shared.Sdk.targets(1269,3): error : clang++ exited with code 1:
2>C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk\16.4.7054\targets\Xamarin.Shared.Sdk.targets(1269,3): error : ld: framework not found System
2>C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk\16.4.7054\targets\Xamarin.Shared.Sdk.targets(1269,3): error : clang: error: linker command failed with exit code 1 (use -v to see invocation)

Has anyone else experienced this and found a solution?

Thanks.

To answer my own questions, it turns out I had to move this line from my referenced project (included in the solution) into main project.

ds.DBPath = System.IO.Path.Combine(FileSystem.Current.AppDataDirectory, "user2.db");

My guess is that the linker wasn't finding all the references.
