How do i update an application after pusblishing it in visual studio

I published an application,when publishing it i che开发者_如何学Ccked that the application should check for updates-now how do i make it realy check for updates-where should i put the new files and in which format?

You'll need it on some kind of Web server.

I would imigine that you also want some authentication so that only the application it self can gain access to the new version of the software.

I'm going to assume you mean you are using CLickOnce as the installer. If you want the app to check for updates every time it is ran you need to publish to a location all the apps can see. If this is an internal app I believe a network share will do. If not then you need to publish to a web server or ftp server.

You can use ClickOnce as nportelli mentioned above, or you can use a 3rd party utility to do the heavy lifting for you.

I wrote an open-source library to do just that transparently - including an external update application to do the actual cold update. See http://www.code972.com/blog/2010/08/nappupdate-application-auto-update-framework-for-dotnet/
