The download link is <a href="http://www.devart.com/dotconnect/mysql/download.html" title="devart" rel="nofollow">http://www.devart.com/dotconnect/mysql/download.html</a> and the docs link is <a href="http://www.devart.com/dotconnect/mysql/docs/" title="devart docs" rel="nofollow">http://www.devart.com/dotconnect/mysql/docs/</a>. At work, another team has used the devart connector the express version and i don't remember them having any problems. Personally, I have only used it in a few tests so i can't say much about it. On the version histoy page you can see that the first version was released in 2002 so i guess it's "trustworthy". And no, i'm not the creator of it :). In both cases the word “here” is a link.

The download link is http://www.devart.com/dotconnect/mysql/download.html and the docs link is http://www.devart.com/dotconnect/mysql/docs/.

Can you show me please? So far is there any other people have use the devart connector? Are you the creator is it? Thank you. Dear Eti,

You can download it <a href="http://www.devart.com/dotconnect/mysql/download.html" title="devart connector" rel="nofollow">here</a>. ( the express version is free and should be enough ) If you wrap all the db operations in a TransactionScope you should have all the operations enlisted in the distributed transaction. As a side note you could use NServiceBus with MSMQ to send/publish the data to be inserted to the remote machines. This way the distributed transaction would be local, coordinating the db call and the local msmq operation instead of remote. Good luck Hi,

So I am now inserting into a local db, one copy to a central db and one more copy to a copy of local db on the central server. How can I achieve this distributed transaction via .net connector? Any help or link will be a great help. Dear All,

Anyhow, make sure you understand the implications of the change. The MySQL transaction is not enlisted in the distributed transaction and if something fails between committing the MySQL transaction and committing the distributed transaction, than the processed message will return to the queue to be re-processed but the MySQL transaction will remain committed. I've been using this in production on pretty heavy loaded systems and i'm yet to encounter a problem related to this. Glad to hear it helped.
