Why is My Debug.Write Output Not Showing in Visual Studio?

System.Diagnostics.Debug.Write Output

The C# program provided in the initial post successfully prints "Hello via Console!" to the console window and "Hello via OutputDebugString" to the DebugView window. However, the output from System.Diagnostics.Debug.Write and Debug.Trace.Write is not visible.

To display output from System.Diagnostics.Debug.WriteLine in the Visual Studio output window, enable the "Redirect all Output Window text to the Immediate Window" option under Tools → Options → Debugging → General. Ensure the "Show All Settings" checkbox is enabled to access this option.

Additionally, System.Diagnostics.Debug.WriteLine output can be directed to specific locations by adding a TraceListener to the Debug.Listeners collection. This allows for more customized and flexible output management.
