It is possible you haven't built the latest build. You can do so by heading to the Build Output option and changing it from Debug to Release.
Afterwards, head to the build menu and select "Build Solution". You should now have the latest build in you bin/release folder (you can verify by checking the Modified date).
Update:
After taking at look at your code you were missing one vital line, "Console.ReadLine();". Without it, you application will execute your Console.WriteLine(); and immediatly exit. "Console.ReadLine();" will allow your program to allow the user to press enter before exiting. Here is the updated code.
