I just installed the ADO.NET connector from here http://dev.mysql.com/downloads/connector/net/
Yet MySQL doesn't appear as a data source like it should. I tried restarting Visual Studio. It doesn't fix my issue. Did I install the wrong connector?
EDIT: STill nothing. I'm using Visual Studio Express For Desktop. Do I need to pay for the Ultimate edition to use a MySQL Data Source?
I was having the same problem just now. I solved it by uninstalling the latest Connector/NET drivers (6.7.4) and then installed the older drivers (6.6.5) and it works.
I am using Visual Studio 2010. I uninstalled the latest ones because I figured they were somehow related to .NET4.5, which I'm not able to use.
