Work has begin on providing a tool to evaluate variables before deployment
At the moment we don’t have further plans to apply config transforms before a release but this should help solve the bigger question of “what will my all my variable values actually be at run time”Boz commented
Really, really need this feature. Have been bitten a few times on releases to production because that is the first time you actually see what variables are replaced on each machine. No number of beta deployments can give you confidence that your Production variables are correct! I actually need to see variable setting by Environment, Machine Role, and Machine. Or at least the option to choose that level of detail and review variables that apply for that scope.
