- Automatic update a Windows application 5 answers
I need to keep a program I've written up to date, this will happen frequently over the next year or so, this will need to be done over the Internet. Where would you suggest I start, are there any common techniques? Any suggestions welcome.
Thanks

Fairly well is not good enough :)
NAppUpdate is an open-source library I wrote to address just this. The general idea is to have the greatest flexibility, at the lowest overhead possible.
So, integration is super-easy, and the library does pretty much everything for you, including synchronizing operations. It is also highly flexible, and lets you determine what tasks to execute and on what conditions - you set the rules. Last by not least is the support for any updates source (web, BitTorrent, etc) and any feed format - whatever is not implemented you can just write by yourself.
Cold updates (requiring an application restart) are also supported, and done automatically unless "hot-swap" is specified for the task.
This all boils down to one DLL, less than 70kb in size.

ClickOnce is perfect for this sort of scenario.

There is this great framework called NetSparkle and also this DotNetUpdater
I haven't used them yet but hope to do so very soon. You can try it out.

ClickOnce is a good solution, but if you wish to have total control then you can roll-your-own. I would suggest polling a webservice to find if there are later versions available, downloading required files to a side-by-side directory, and using a launcher (or updating a shortcut) to automatically launch the latest version.
This is a little complicated, but caters for situations where the application may be running, and can therefore not be overwritten.
