Entity Data Model Wizard error using vs2010 and mysql 5.4.3

Post by martincho » Sun 20 Dec 2009 14:02

Hi, I'm trying to generate an EF model from a mysql db version 5.4.3 and the connection test of the wizard first step works fine, but in the second step when try to retrieve the database information get the following error

An error occurred while connecting to the database. The database might be unavailable. An exception of type 'System.Data.EntityCommandExecutionException' occurred. The error message is: 'An error occurred while executing the command definition. See the inner exception for details.
The inner exception caught was of type 'System.ArgumentException', with this error message: 'Could not determine storage version; a valid storage connection or a version hint is required.'.'

Seems like is related to the db version. Anybody knows if must configure an additional parameter in the connection?

Thanks in advance.
