The name 'Console' does not exist in the current context In xamarin forms app

Since your code is in a PCL with a specific profile the System.Console isn't available.

Use Debug.WriteLine("Text here") instead, don't forget to add using System.Diagnostics;.

The "Console" function is only available if you create a Console App(.NET Core) or (.Net Framework); so, if you for example create a Blank App, it is not going to work. But instead, you can use the Debug function.
