In my VB.NET Console App, i want to use timers for multithreading functionality. this is my Sub Main

VB Code:
  1. Sub Main()
  2.         tmrMain.Enabled = True
  3.         tmrMain.Interval = 3000
  4.     End Sub

But the application starts and ends, which means that there should be a way to make the console applications wait and pass control to other threads ! how do i do that ?
