I have a vs solution with:
One class library with custom activities.
One sharepoint project with a mapped folder to the workflow folder in the 14 hive and the custom actions entries.
One sharepoint project with a feature that adds the authorized type to the web.config.
From my point of view this makes maintenance and subsequent deployments easier because: If I add a new custom activity, I only need to update solution 2. not number 3.
What do you think? Would it be better to join 2+3 in one simple sharepoint project?
is there any ms article or blog that talks about this?
