Display a message in Visual Studio's output window when not debug mode?

Question

In Java, you can use System.out.println(message) to print a message to the output window.

What's the equivalent in Visual Studio ?

I know when I'm in debug mode I can use this to see the message in the output window:

Debug.WriteLine("Debug : User_Id = "+Session["User_Id"]); System.Diagnostics.Trace.WriteLine("Debug : User_Id = "+Session["User_Id"]); 

How can this be done without debugging in Visual Studio?

Answer 1

The results are not in the Output window but in the Test Results Detail (TestResult Pane at the bottom, right click on on Test Results and go to TestResultDetails).

This works with Debug.WriteLine and Console.WriteLine.
