Hello. Is an extension project required for use in the workflow API? I don’t see this question answered in the training class, although it’s example uses the extension library. When building a workflow code file for use in the website App_Runtime folder (instead of a .Net library), an error happens in a transition. I’m unsure if the ambiguity is legitimate or not.
