Writing to output window of Visual Studio

Add the System.Diagnostics namespace, and then you can use Debug.WriteLine() to quickly print a message to the output window of the IDE. For more details, please refer to these:

  • How to trace and debug in Visual C#
  • A Treatise on Using Debug and Trace classes, including Exception Handling

This will write to the debug output window:

using System.Diagnostics;

Debug.WriteLine("Send to debug output.");
