.Net Console Application that Doesn’t Bring up a Console
I have a console application written in VB.NET that will become a scheduled task on a web server. It will run every ten minutes. The problem is that every ten minutes it displays the empty black CMD window while processing, which can be distracting. How can I configure it to run in the background (with no CMD window displayed)?
Set on your Project in "Application" the Output Type to "Windows Application".
