Hello, I have made a ClickOnce Full trust application with VS2010 and .NET 4.0 Client Profile. The
application manifest and even the EXE file is signed with a valid publisher certificate.
The publisher is recognized and the certificate chain is accepted during install. A Medium-risk dialog is shown (because of the Full trust) and program shortcuts are created. Everything is ok.
After clicking the program shortcut in Windows 8 the certificate is no more recognized. Just like the EXE file would not be signed. A warning prompt is shown saying the ...exe is from an Unknown Publisher and it would be a security risk to
In Windows XP and 7 there is no such issue.
Googling for "ClickOnce Trust Manager indicates an unknown publisher in security warning" I have found the following article:
If it is a bug in Windows 8? When it will be fixed?
Does ClickOnce in Windows 8 accept no more certificates with the hash algorithm SHA1 but the stronger SHA2?
How can I discard showing the warning message not involving end users into this process in Windows 8?
