ah, michael!
this is a point of confusion with the trusted signing preview. it can be a bit tricky to navigate ))
the issue is that even with the microsoft.codesigning resource provider registered, access to the code signing profile preview might still be gated. this feature often requires an explicit enrollment or for your subscription to be allow-listed by microsoft.
the first thing to do is check the official sign-up page for the preview. if you have already done that, the next step is to contact azure support directly. they can check your subscription status and manually enable the code signing profiles for you. be sure to tell them you have already registered the resource provider but only see attestation options.
also, double check the region where you are creating the trusted signing resource. the code signing preview might only be available in certain azure regions right now, like east us or west europe. trying a different region could make the option appear.
hope you get access soon. that code signing feature is a game-changer for devops security.
Best regards,
Alex
