Answer 1

You can generate a ClickOnce certificate with any expiration date (and any Issued To/Issued By values):

makecert -sv ClickOnceTestApp.pvk
     -n CN=Sample ClickOnceTestApp.cer
     -b 01/01/2012 -e 12/31/2100 -r

It will be a self-signed certificate, same as generated by Visual Studio for click once deployments.
