Add a link to the app in programs menu on install
I was a little surpursed when i installed the app that it was not in the program list. Granted it is small and i typically use the autocomplete to find and launch apps but it does make me question future maintenance, uninstall and clean up issues.
Are you sure you ran the setup and not the standalone executable?
When installed, LINQPad appears in the program list as "LINQPad" or "LINQPad 4".
