The GPL is a distribution license. This means that the license kicks in when you distribute code which uses GPL-ed code: it in effect limits your distribution rights of the GPLed code with your software in such a way that if you don't obey to the license' terms, you can't distribute nor USE the software.

So if you use a GPLed library in your app A, and you distribute A to your client, you can only do so if A meets the requirements of the GPL, as you distribute A and A uses a GPL-ed library. This thus means that you have to GPL license A. If A is used internally by the client, no problem unless you don't want to deliver the sourcecode to the client. If your client uses the software in their software and distribute A with their app, you do have a problem.

I know, this is a restrictive matter, but that's what the GPL does. So unless you're tied to MySql, use Postgresql. :) Better database, provider isn't GPLed (LGPL in fact, so you can distribute as binary) and less headaches.

So are you more "pro" for the free connector, and more "con" for the MyDirect.NET stuff?
No. the 'free' connector isn't free: it's GPL-ed. This means you either have to open source / GPL your own software OR pay a huge fee to MySql for every license you need. That's stupid as MySql should be interested in as much people connecting to their database. Apparently not.

The Corelab connector isn't free, but it's the cheapest around. So unless you want to GPL your own work, it's the 'best' option around. 'best' is subjective here, as neither connector is really that solid.

I am an ASP.NET developer looking to use MySQL as my primary database.

I installed the latest version of the MySQL Connector (5.2). It seems to work out of the box with Visual Studio 2008. I can create tables, modify them, add data, create datasets, etc...
... and is GPL licensed, or have they changed that lately? The non-GPL licensed version is kind of expensive, 250+ euro per seat. Don't think lightly about the GPL license, it does force your own software to be GPL-ed as well if you distribute it, which means if you transfer it to another system (e.g. the production server of your client) you've to open up the sourcecode.

Has anyone used Devart's MyDirect.NET and/or dbForgeFusion for MySQL? If so, what are your thoughts on it? Is it worth the $$$$ or should I just stick with the FREE MySQL Connector?

(Link: http://www.devart.com/)
We use it in our mysql driver/SQL engine in llblgen pro. Core Lab, the previous name of 'DevArt', isn't really good in doing support but MySql itself is also a pain in the neck concerning support. mydirect costs money but way less than MySql's own connector.

Personally I find it rediculous to pay for a connector to a database system: the db is worthless without the possibility of making a connection, so why charge for a connector? MySql should release its provider under teh LGPL, which is the license intended for libraries, which is exactly what the connector is.
