I need to make some changes to a ClickOnce application that I haven\'t touched for over a year and therefore the certificate has expired.
I\'ve read that publishing
Here's the definitive MSDN article on certificate expiration, which also includes a link to an update on RenewCert. http://msdn.microsoft.com/en-us/library/ff369721.aspx This covers all cases.
If you are targeting .NET 3.5, using automatic updates, and don't have a VSTO app, OR you are targeting .NET 4, changing the certificate will not cause you any problems.
