Probably you are not closing or disposing the connection object. You can use the same connection object which is open or close it open new connection (if different connection string).

Here's the solution I found. I installed 6.9.8 and everything has worked perfectly since.

I have the same issue that came up when I first deleted the existing connection from Solution explorer. Ever since I am not able to use data source configuration wizard. It keeps giving me message that "Some updating commands could not generated automatically. The database returned the following error: You have a usable connection already. Any help is appreciated.

This is not an open discussion, even if problem is the same, you should create a new question and delete this Solution.
