When I created the List Instance in visual studio 2010. The first deployment is successful but when again I deploy that solution I got the error message:
“The URL or name of this list instance conflicts with a list instance already on the server. The list instance on the server will be deleted before deploying the new list instance”.
First, we select the list definition name and expand that list and select the List instance and now open properties. In the property we able to See Deployment Conflict Resolution. When you then click that than the dropdown list is open and you see there are three options:
1. None: Keep it your existed list with an item (If a list is not there that list will be created).
2. Prompt: Give the error message with Prompt (See in fig 1)
3. Automatic: Automatic deletes the existing list.
By default is Prompt. So if you want to delete the already existed list in the server than Select Automatic. And if you want to keep it your existed list with the item then select None. So the best solution is to keep it as a NONE.
Hope this will help you !!!
