So far, I have had huge issues with my beta testers: the moment they removed Daily Quote for PocketPC, their PocketPC popped up a highly annoying alert about “File not found” whenever it powered up. Yikes. I have no idea why Windows Mobile can’t purge unneeded notifications like the Palm OS can – but hey, its Windows Mobile…
The ideal solution would involve a single API call being called at program removal: as the program gets kicked off the handheld, a single call is called, thereby eliminating any and all notifications still lingering around. Unfortunately, this is not possible with the .NET CF – the solution is called Setup.dll and requires native code. While I am completely dumbfounded as to why native code is required, the only reason I can think off is that Microsoft wants to make sure that the dll is run even if the .NET framework is not installed.
José Gallardo Salazar has posted a lovely overview of the process to his blog – hit the link below for the full scoop while I try to figure out how it all works:

P.S. A template for a custom Setup.dll can be downloaded here.
