Try: Console.WriteLine (type out for a Visual Studio or Rider snippet)
Console.WriteLine(stuff);
Another way is to use System.Diagnostics.Debug.WriteLine:
System.Diagnostics.Debug.WriteLine(stuff);
Debug.WriteLine may suit better for Output window in IDE because it will be rendered for both Console and Windows applications. Whereas Console.WriteLine won’t be rendered in Output window but only in the Console itself in case of Console Application type.
Another difference is that Debug.WriteLine will not print anything in Release configuration.
