my distributed program need update couple of files, i would like it to work the way like those anti virus software updating there virus definition database, is there such framework?
Edit:
It really depends on the how your data is formatted. If you're keeping a simple local storage in text files, then it's just a matter of hitting up a server and checking if there is a new version of the file(s). If you're keeping things in local SQL storage, then you could use web services to ensure the local storage has the most up-to-date entries. I think that option is what you're looking for, and it would be really easy to write. However, if you're looking to update applications, then something like ClickOnce might be ideal.
In response to your edits Basically, you have to structure your application to read all information from information files and give those files some meta-information like a "version number" or something like that. Then, you have an ASP.NET web service which has two functions: one is to get the latest version of the information files and the second is to download the updates needed to patch from one version to the current. So, the application would intermittently check with the server to see if there is a newer version than what they have. If there is a newer one, then it would ask the server for the patch files needed to get to the latest version. If you do this before the application actually starts (a la Firefox), the user doesn't even have to notice that the application is restarting.
As far as I know, I am not aware of such a framework. However, the magical stuff is done by Web services or Windows Services looking for updates at a HTTP or FTP location. You might perhaps wirte yourself a code that would launch the script you deploy with your update.
Perhaps this would help a bit: Loading Assemblies. In short, this is the way plugins are plugged in your application, using proxies and so forth.
As mentioned by @Travis G, ClickOnce is good for application. Just different approach! =)
