Hi Guys,
I have an WPF App that we deploy on a regular basis. Is there a way to uninstall the version on client's desktop before installing the new version.
Thanks
Reeves

Hi Reeves Edward,

ClickOnce has auto update feature that enable you to upgrade to a new version without uninstall the previous one. Once you publish a new version to that special URL, your user will receive update information when they run the installed application. They won't be told to uninstall and after several minutes(it depend on your application size and download speed) their application will come with updated one.

Does that what you want?

Sincerely,
Kira Qian
