This is a recurring request on Microsoft's ILM forum. So, I put a link to the source here such that folks can get to it without needing to ask. To make everything work, don’t forget to download the SQL.NET Connector from http://dev.mysql.com/doc/refman/5.0/en/connector-net.html as well. Oh, and if you came here through the ILM forum, mark that post as helpful to bump it up the list.
All this of course with thanks to the original author (whoever you may be - if you stumble on this, please leave a comment such that I can credit you properly!)
