Explanation others:
As given in the question, the application’s users increase eventually and you are required to ensure that all users make use of the same version of the application. Therefore, you change the application to use the ClickOnce deployment. ClickOnce is a deployment technology that allows a user to create self-updating Windows- based applications.
It can be used to create applications that are installed and executed with minimal user interaction. It can also be used to create applications that are easily deployed from a Web site, a file share, or a CD-ROM.
ClickOnce technology overcomes three major deployment issues as follows:
. Difficulties in updating Windows-based applications
. Dependence of multiple application programs on shared components
. Allowing permissions only to administrative users for application installations
