Why Doesn't Console.WriteLine() Work in WPF Applications, and What's the Alternative?

Troubleshooting Console Output in WPF Applications

WPF developers often find Console.WriteLine() ineffective when debugging from the command line. This stems from a common misconception about its application.

Console.WriteLine() is specifically designed for console applications, not WPF applications. For debugging output within a WPF application, the correct method is Trace.WriteLine(). This sends debugging information to the Visual Studio "Output" window.

Remember to include the System.Diagnostics namespace using using System.Diagnostics; to access Trace.WriteLine().

Illustrative Example:

<code class="language-csharp">using System.Diagnostics;

class Program
{
    static void Main()
    {
        Trace.WriteLine("This message will appear in the Visual Studio Output window.");
    }
}</code>
