I’ve followed this discussion on StackOverflow and went to Windows Identity Foundation, as advised, to download WIF. The best match for my OS is Win 8, so I downloaded the file, Windows6.1-KB974405-x64.msu. This has worked so far with drivers and such, so it was worth a shot.
However, as I start the installation process the computer complains about encountered error 0x80096002: “The certificate for the signer of the message is invalid or not found”.
Does it have to do with wrong version of OS? How can I dance around this problem?
WIF has been integrated in the OS on Net 4.5 under System.IdentityModel and System.IdentityModel.Services dlls. No need to download anything else.
