    Most likely this is caused by the GetConnection method not finding the assembly referenced in the config file. This is probably caused by not referencing the assembly, or possibly the assembly name is misspelled.

    Verify that the assembly is in the references collection of the project. Let me know if you continue to have problems.

      Ok. It's working now. Thanks. The assembly name was misspelled. And congratulations for the script. I've seen some aproaches of this kind but yours is the simplest one.
