What is ClickOnce

October 2, 2011

The Microsoft technology Clickonce is technology that enables clicking a link on a website and installing software. It has been a component of the .NET framework since version 2.0. ClickOnce is similar to Java WebStart and GNU/Linux ZeroConfig.

ClickOnce is supported natively by Internet Explorer and Firefox via a Firefox plugin.

There is also a provision in the ClickOnce architecture to automatically update applications. Applications can be configured to check for updates automatically at startup or after startup. ClickOnce also provides API’s for further controlling the update process.
