after installing trial version I get this message:

Failed to create an instance of 'CoreLab.MyDac.TMyConnection' because 'System.MissingMethodException: Constructor voor type CoreLab.MyDac.TMyConnection is niet gevonden.
at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes)
at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes)
at Borland.Studio.Host.CreationManager.a(Type , Object[] , Type[] , Boolean )'.

How do I solve this?

Unfortunately we couldn't reproduce the problem.
Try to uninstall current version of MyDAC you use. Then download and install the latest version of MyDAC (4.30.1.14).

the problem is not MySQL DAC, this is working fine.
The problem occurs in MySQLDirect.NET
and you still want me to update DAC?

The problem occurs in MySQLDirect.NET

Are you talking about this error:

Failed to create an instance of 'CoreLab.MyDac.TMyConnection' because 'System.MissingMethodException: Constructor voor type CoreLab.MyDac.TMyConnection is niet gevonden.

There is no TMyConnection class in MySQLDirect .NET.
Could you please describe the problem in details and send us your test project to reproduce it (do not use third-party components, include definitions of your own database objects).
