I have created 4 webparts each in their own solutions and they work great. How could I add each webpart to an empty solution and deploy them as one feature & have each web-part available indiviually . Everything I read on how-to gives steps that seem incorrect and are very different from each other.
-I think I 'add existing items' and add the .webpart file [would I need anything else? .cs? .wsp?]
-then add a new feature & give it a element for each .webpart
-will I need to edit the manifest.xml? or anything else?
