I have this project with custom field for a content type.
When I deploy the first time after creating the new field everything is fine. Once i retract the solution my field is the only one left on the site, it wont retract. When i publish after that i get this error
"The field with Id {1ef18d86-3fe6-4c8c-b22a-377c2e98c17d} defined in feature {03118f5c-a57b-40f8-b908-c9c8d3174f01} was found in the current site collection or in a subsite"
And a warning saying pretty much the same thing.
