Well, I have got the same problem as this guy with the equally titled thread.
I want to add a SharePoint 2013 Workflow to my App Web. It is a list Workflow. Workflow Manager and Service Bus are installed and configured correctly.
When I create a Workflow and want to debug/deploy the App, the Workflow is not listed as Workflow in the List.
I don't know why, I don't know if its a development or a server configuration issue.
Has someone had the same problem, but solved it?
(Everything is programmed in Visual Studio 2012. Lists, and Workflows, too)
Thank you, Loki
