I’ve seen this error come up a few times now, and there’s a (dirty, ugly) hack you can use to fix it. So, for those who are fans of dirty, ugly hacks, here you go.
If you see the error:
ACM encountered the following error while performing synchronization:
Violation of PRIMARY KEY constraint ‘IssueSolution_PrimaryKey’.
Cannot insert duplicate key in object ‘dbo.IssueSolution’.
The statement has been terminated.
Would you like to retry?
You can fix it by (remember, I said it was a dirty, ugly hack) removing the constraint:
ALTER TABLE [dbo].[IssueSolution] DROP CONSTRAINT [IssueSolution_PrimaryKey]
Good luck, and sorry for the bug.
