mysql connector/net 6.0.1 beta has been released

MySQL Connector/Net 6.0.1, a new version of the all-managed .NET driver for MySQL has been released. This is a beta release and is intended to introduce you to the new features and enhancements we are planning. This release should not be used in a production environment.

We had three major goals with this release. Speed, Entity Framework support, and a better Visual Studio experience. I'm happy to report that we have met all three. Please see the complete list of changes below.

It is now available in source and binary form from [] and mirror sites (note that not all mirror sites may be up to date at this point of time - if you can't find this version on some mirror, please try again later or choose another download site.)

  • Massive speedups. We have increased the speed of the provider. In many situations it now matches or exceeds the speed of the native C connector.
  • SQL tokenizing has been improved dramatically. Not only is it substantially faster (approx 40%) it also now uses a completely rewritten tokenizer that supports all types of stored procedure comments.
  • Added UDF schema collection
  • Implement initial Entity Framework support (see below)
  • Improved Visual Studio integration (see below)

Entity Framework support
Yes, we are late to the party but we are here. I apologize for the delays related to this release and I hope that those of you looking to use MySQL with the entity framework will still want to give us a look. This releases uses a entity framework engine that was completely developed in-house and is, therefore, licensed in exactly the same way as our core provider. Please remember that this is an alpha release and we are certain that you will find databases that will not reverse-engineer correctly or you will build models or queries that will not generate correctly. Please file those as bug reports and include all the information you can. We'll quickly get to those as we are going to move as quickly as possible to GA.

Visual Studio improvements
We have completely rewritten our Visual Studio integration bits and are delivering several exciting features with it. Here's a look at some of those features:

1. Now uses the same toolbars and commands as SQL Server so the integration is much more seamless.
2. Uses the native code editor which means code splitting and syntax highlighting.
3. Change script generation
4. And many more smaller features.....

Please take this version for a test drive and let us know what works and what doesn't.


  1. Hi Reggie:

    Don't know if you remember me, but we met at MySQL Conference 2007 and discussed your work on this connector.

    I'm finally making a serious stab at learning to separate content from presentation and thus completely making over a site in ASP.Net. Anyway, I had a couple early problems and took one to the ASP.Net forum rather than bother you.

    Interestingly enough, your connector came up in the discussion AFTER a solution was discovered.

    I've given you a nod (with link, of course!) in my most recent post to the thread:

    It's good to see you are doing well and the connector is making such great improvements. [I'll try it as soon as the site is reliably running with the trusty ODBC connector -- which doesn't require me to learn too much more all at once. ;-) ]

    We missed you at MySQL Conference last year. I hope your knee is healed and you are completely mobile!

    Thanks for the sharing..

  3. The license for this driver is GPL. What does this means? That any application using it also needs to be GPLed?

    I know that any changes i make to the driver I do need to make them available using the GPL license.

    An insert and update error was generated by the decimal data type in the Entity Framework, when a German collation was used. (Bug#43574)

  5. This release was quickly pushed out due to a problem that caused 6.0.1 to not register with Visual Studio correctly.

  6. Thanks for update.. just having a problem can't open link in firefox any help.

    Definitely a great release.

  11. I like how you write.Are you interesting in a part time writer job?

  12. In the MVC Framework, a URL is seen as the mean to address a logical server resource, but not necessarily an ASPX file to parse. So the URLs employed by the pages of an MVC Framework application have a custom format that the application itself mandates.

  13. Hi,
    If Christian Audigier is making a kids clothing line, you best believe the prices are going to be outrageous. I will never understand how a t-shirt is worth over a hundred bucks. There is no type of sewing or screen printing worth that much.

  14. How to insert the to uppercase command in HTML forms?
