I am sure others will find that partly useful, as the complete how to is more complex than that, for one you have to install xset, mono and visual basic first, and set the OS to auto login, I never knew about unclutter, usually just set the cursor to a blank one, thanks for that tip.
Some tips, for people that try this.
you can still get to the command line, if you press ctrl+c when starting up, at the point it says "type startx"
to use a vb.net app install mono on windows and copy the Microsoft.VisualBasic.dll from windows to linux, placed next to your app, mono-complete does not include visual basic, go figure not so complete.
don't use any mono less than 2.10, it's just a pain in the compatibility.
I still have not found a way to make a full screen windowed app, that covers the task bar the same way it does on windows, you would think it would work the same as it does on windows, should submit it as a bug to the mono team.
