How to repeat:
Create a MySqlConnection object to a v3.23.49-nt database and launch a GetSchema("Columns"); command

Hi Roger and thanks for your report.

Please notice that MySQL server 3.23 is long eol-ed and was never, afair, supported by c/NET. Use Mysql server 4.1 or newer instead.

Sorry, I wouldn't have bothered you guys if I knew this. I thought the version 3.23 was still supported because my Connector documentation says this :

"MySQL compatibility 
Connector/Net fully supports all GA versions of MySQL from 3.23 to 5.0. Connector/Net also supports the latest pre-release versions of MySQL 5.1 and 6.0. "

But now it's clear, it's OK. Thanks anyway.

PS : Someone should update the documentation ;)

Roger, where did you find that quote? http://dev.mysql.com/doc/refman/5.1/en/connector-net-versions.html says:
      *

      Connector/NET 1.0 includes support for MySQL 4.0, and MySQL 5.0 features, and full compatibility with the ADO.NET driver interface.

      Connector/NET 5.0 includes support for MySQL 4.0, MySQL 4.1, MySQL 5.0 and MySQL 5.1 features. Connector/NET 5.0 also includes full support for the ADO.Net 2.0 interfaces and subclasses, includes support for the usage advisor and performance monitor (PerfMon) hooks.

      Connector/NET 5.1 includes support for MySQL 4.0, MySQL 5.0, MySQL 5.1 and MySQL 6.0 (Falcon Preview) features. Connector/NET 5.1 also includes support for a new membership/role provider, Compact Framework 2.0, a new stored procedure parser and improvements to GetSchema. Connector/NET 5.1 also includes the Visual Studio Plugin as a standard installable component.

I really doubt anyone is actually testing latest versions not only against 3.23 but against 4.0 too.

I'm afraid I can't quote with an url like you did,

however, I can tell you how I found it.

I downloaded the package Connector/Net 5.2.5 (windows binaries) from http://dev.mysql.com/downloads/connector/net/5.2.html

After having installed the .msi in the archive, I have a file MySql.Data.chm in the Documentation folder of the installation which says the lines I've quoted in the "Compatibility" section.

I also found the file "Documentation/Content/Compatibility.html" in the Sources archive at the same url.

Roger, thanks for following up. I have assigned Tony to fix this in docs.

Thanks for your interest in MySQL!

It looks like the problem is in Reggie's source code/docs/CHM, not the doc team documentation XML source. Passing to Reggie for review.

Fixed in 5.2.8, 6.0.5, and 6.1.1

Entries were added to the 5.2.8, 6.0.5 and 6.1.1 changelogs:

MySQL Connector/NET CHM documentation stated that MySQL Server 3.23 was supported.
