Hello, i am writting an application that runs on mono. I am using the mysql net 4.50

My application runs well with mono 1.26, but i tried to run it with the new mono 1.9 and crash with this problem:

Unhandled Exception: System.InvalidCastException: Cannot cast from source type to destination type.

at Datos.DsUsuariosTableAdapters.usuariosTableAdapter.GetDataxCedula (System.String CEDULA) [0x00000]

The problem just appears when i have to make a query on my database with the MyDirect.Net connector. The rest works fine.

The version of mono is:
Mono JIT compiler version 1.9 (tarball)

TLS: __thread

PLEASE HELP ME!

Unfortunately, we have not tested the product with this fresh version of MONO.
Please send me a small test project to reproduce the problem.
It is desirable to use 'test' schema objects, otherwise include the
definition of your own database objects.
Do not use third party components.
If it is impossible for you to create the test project, send us a piece of
your code where the error occurs.
It will help us greatly.
