How to debug?

[EmkioA]

as stated earlier, no break point possible.

alert() is not working too.

Why use JavaScript as language, we are into Visual Studio, why not use c# and/or vb?

I've found I can do rudimentary print-style debugging via the VS Output window:

var vsWindowKindOutput = "{34E76E81-EE4A-11D0-AE2E-00A0C90FFFC3}";

var outputWindow  = dte.Windows.Item( vsWindowKindOutput );
outputWindow.Activate();

var outputWindow2 = outputWindow.Object; // <-- Weird: https://learn.microsoft.com/en-us/dotnet/api/envdte.outputwindowpanes
var outputPane1   = outputWindow2.ActivePane;
var outputPane2   = outputWindow2.OutputWindowPanes.Item( 1 /* name */ );

outputPane1.Activate(); // <-- Is this necessary?
outputPane1.OutputString( new Date() );
outputPane1.OutputString( "\r\n" );

(This code currently re-uses the current Output pane as I'm having problems with OutputWindowPanes.Add( "MyMacro Output" ) not working reliably.
