In VB.NET 2005 how do u specify Module Subroutine as Application startup routine?

Under Project Application Properties it gives you the option to select Startup Form but no option to say use VB Module Subroutine instead?
You could do this in VB6, any ideas guys? I'm new to VB.NET.

Or is it that your vb.net applications have to start of in a Form?

Thanks
