How to repeat:
I have repeated this error in another machine with same configuration:
Win2k Sp4, .Net framework 1.1, MySql 5.0, Connector 1.0.6. Visual Studio 2003.
I can't even execute the example included with connector!.

Hello, I also have this problem, but only when I execute the application from the VS. I attach trace files and my test case (VS project). Thanks.

Hello,
this is my first trial with .net Connector; it's the same environment, with the same
problem.
MSVP advises to use a 2rd party Connector, but this cannot be the solution.

Thank you
Willi
