MySQL Connector/Net 5.1.2 Beta has been released

MySQL Connector/Net 5.1.2 a new version of the all-managed .NET driver for MySQL has been released.

Connector/Net 5.1 represents a change in how we package our products. Until now, we've shipped our core provider and the Visual Studio integration bits as separate downloads. This has become a bit of a problem. Often we would fix a bug that involved changing code both in the VS package and in the core provider. This provided a versioning problem where users would need to upgrade both products to see the benefit of the bug fix. To solve this, we've decided to discontinue Tools for Visual Studio as a separate product and have, instead, integrated it into a new Connector/Net installer. We hope this provides a better "out of box" experience for our users.

All previous versions of Tools for Visual Studio should be uninstalled prior to installing this product.

Version 5.1.2 works with all versions of MySQL including MySQL-4.1, MySQL-5.0, MySQL-5.1 beta or the MySQL-6.0 Falcon "Preview". Please be aware that this version is beta quality software and should not be used in production environments.

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.)

Issues fixed

  • Fixed integration with the Website Administration Tool.  Before this fix, the test link was visible but did not work and  user management did not work.
  • Reintroduced code to properly return field values as byte[] when the binary flag is present. (See release notes)
  • Fixed problem preventing the DataSet Designer or TableAdapter wizard from being able to generate insert, update, and delete statements. (Bug #26347)
  • Fixed problem preventing use of stored procedures for insert, update, and delete statements in a table adapter.
  • Fixed problem where text columns would not appear in the Visual Studio query builder (Bug #28437)

Bugs fixed in 5.0.8 that are now appearing in 5.1.2

  • Log messages are no longer truncated to 300 characters (Bug #28706)
  • Fixed a problem with compression over a network.  We were letting the inflate stream read directly from the network stream.  Under certain situations, two bytes were being left unread and this messed up our byte counts.  Now we are using a WeakReference to an internal buffer that we read the compressed data into before inflating. (Bug #28204)
  • Fixed problem where we were not closing prepared statement handles when commands are disposed.

  1. Hi Reggie,

    Connector.Net and MySql are great. But I can't understand how on earth is it possible that, on MySQL's web page (, 5.1.2 is *not at all* declared as beta but as a normal, production release. Unless I'm missing some disclaimer somewhere, this us trully surprising. Safefully, there is your blog, but how many know it?

    Moreover, I find it quite hard to believe that a version, even a beta, is released with so many regressions ("Bugs fixed in 5.0.8 that are now appearing in 5.1.2").
