Trace listener is not generating log file

I'm supposed to be getting a trace listener file like log.txt (as stated in the book I'm currently reading)

But it's not happening for me. Please tell me how I can fix this?

I've not done anything similar to this in the past.

// Write to a text file in the project folder 
Trace.Listeners.Add(new TextWriterTraceListener(File.CreateText("log.txt")));

// Text writer is buffered, so this option calls Flush() on all 
// listeners after writing
Trace.AutoFlush = true;
Trace.WriteLine("Trace says I'm watching.");

Solution

Please tell how I can fix this.

There is no fixing needed really. The file is created and you message is in there, you are simply looking at the wrong site for the file.

Since you gave only a filename it is going to be in the program working directory, (which can be different from the exe location, even if in most cases they will be the same). But take at first a look at the same folder as the *.exe file is in. If you want the log file to be saved in a specific place you need to define the entire path:
