Database Explorer shows System.Byte[] against all tables

Post by albievg » Thu 11 Nov 2010 11:34

I have the latest version of dotConnect for MySQL (4 Nov 2010) within VS 2008, .NET 3.5.

After creating a connection to the desired MySQL database, when I expand the Tables within the Database Explorer, all tables are listed with the name "System.Byte[]"

In VS 2010 I get similar behaviour except that in stead of all tables being listed only one table is listed in the Database Explorer as "System.Byte[]".

Any ideas on how to fix this?

The problem may be caused by an installation error. Please try performing the following:
- uninstall dotConnect for MySQL;
- remove all Devart.* and policy.*.Devart.* files from the GAC;
- clear the Program Files\Devart\dotConnect and Program Files\Common Files\Devart\ folders;
- re-install dotConnect for MySQL.

If the problem persists, please specify
- the version of the MySQL server you are connecting to;
- the character sets used at the server and specified in the connection settings;
- the editions of Visual Studios installed on your machine.

Also, you can try the new 6.0.46 Beta build of dotConnect for MySQL that we have released recently. It can be downloaded from
(the trial version) or from Registered Users' Area (for users with active subscription only):
For the information about the new features available in dotConnect for MySQL Beta, please refer to

Thanks Stanislav

After removing the existing folders in Program Files and reinstalling the beta version it now works again.
