This is all Visual Studio related (no SPD).
- I created a SharePoint 2013 farm solution containing one custom workflow activity (declarative, no code). The solutions is called "ResuableWorkflowActivities.wsp".
- Next I created another SP 2013 farm solution and added a reference to my ReusableWorkflowActivities project.
- In the toolbar I can see my custom workflow activity. Unfortunately I cannot drag it onto the designer surface. It won't allow me to :(
The question is: Is it possible to create a "reusable workflow activities" SharePoint solution? Or do activities need to be placed in the same project as the workflow consuming them?
I have no doubt it does work with coded workflow activities. If I can avoid it I'd rather use declarative actions though.
Edit: I added an answer and would be glad to receive any feedback as I cannot tell if this is just working for me - hopefully not :)
