I am developing an application in ServiceStack and am trying to sort out deployment on AppHarbor, however for some reason my web.config transforms are not being applied.
I stumbled across this post because I was seeing the same lack of action myself. Upon closer inspection (about 15 times that is) of my Web.Release.config I realized one of the nodes in my config file was not marked xdt:Transform="Replace". Unsurprisingly it did nothing when deployed.
