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 with a new certificate will make the application fail, because it will be signed with a different key.

Therefore I think I need to use the same certificate but not sure how to renew it.

If you're after a quick solution, then you can "renew" your existing certificate and just give it a longer expiry date.

Cliff Stanford has cleaned up the Microsoft "workaround" and made it available as a simple command line exe - available here: http://may.be/renewcert/ - Nice work Cliff !
