MySQL Connector/Net 1.0.8 RC has been released


MySQL Connector/Net 1.0.8 RC has been released.  MySQL Connector/Net is an all-managed ADO.Net provider for MySQL.  While this release is suitable for any version of MySQL, it is strongly encouraged that this release not be used on any production data. 

We are making this release available as an RC because there were significant changes made to the provider beyond just simple bug fixes.  Due to this, we felt it prudent to ask for feedback from the community before declaring the provider safe for production use.  We plan to release the next version (1.0.9) as GA within the next 2-3 weeks incorporating any feedback we get from the community.

It is now available in source and binary form from the Connector/Net download pages at 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.)

This release includes many bug fixes along with the following enhancements/changes:

  • Implemented a stored procedure cache.  By default, the connector caches the metadata for the last 25 procedures that are seen.  You can change the number of procedures that are cached by using the 'procedure cache=<size>' connection string setting.  You can disable the procedure cache by setting a zero size. 
  • Executing stored procedure now no longer requires the user to have a select privileges on the mysql.proc table.
  • Shared memory connections now work as expected.
  • Queries containing a large number of parameters now run many times faster than before.  As an example of the performance gains seen, an internal testing app that needed more than 30 minutes to execute using 1.0.7 now completes in less than 8 seconds.
  • We are no longer providing binaries compiled with .NET 1.0.  We are doing this for a couple of reasons.  First, we believe the majority of our users are using .NET 1.1 or 2.0.  Also, removing .NET 1.0 binaries reduces the number of frameworks we have to test thereby reducing the time it takes to verify releases.  If 1.0 is needed by a sufficiently large number of users, we are willing to re-evaluate this decision.
  • The ICSharpCode ZipLib is no longer used by the connector and is no longer being distributed with it.

The installer for this release installs the assembly into the Global Assembly Cache (GAC) without giving you an option to not do this.  In the GA release (1.0.9), the installer will include an option to not register the provider in the GAC. 

Also, the installer attempts to install both 1.1 and 2.0 binaries into the respective GAC.  If you do not have both frameworks installed, the installer will give an error.  This will be fixed in the final product but for now you can work around this by doing a custom install and choosing the version of the driver for the framework you want to install.

Thank you for checking out this release of Connector/Net. 


  1. Hi,
    could you give me some examples of using

    For caching server config:
    &quot;cache server configuration&quot; -OR-
    &quot;cacheserverconfig&quot; -OR-

    and for resetting the connection:
    &quot;reset pooled connections&quot; -OR-
    &quot;resetpooledconnections&quot; -OR-
    &quot;reset connections&quot;

    for speed-up the connections ???
    Thanks in advance
