Exception Entity Framework 4 exception was not

I am connecting to a MySQL database from Visual Studio 2010 using Net / Connector.

This is the linq interface request 4 linq:

        int timeThreshold = 5;
        DateTime cutoffTime = DateTime.Now.AddMinutes(-timeThreshold);

        try
        {
            using (var context = new myEntities())
            {

                var unprocessedMessages = from m in context.messages
                                          where m.createdDate < cutoffTime
                                          select m;

            }
        }
        catch (Exception e)
        {
            string exceptionString = e.InnerException.ToString();
        }

An exception is thrown in the Results view of the extended unprocessedMessages:

  • base {"An error occurred while executing the command definition. For more information, see the internal exception."} System.Data.EntityException {System.Data.EntityCommandExecutionException}

I am trying to understand what an internal exception is. However, the catch block is never entered. What's going on here?
