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.

Thank you for the report, we are investigating the situation.
I will let you know about the results.

The problem is fixed, look forward to the nearest build.

Same error message and setup when adding the ADO.net Entity Data model.
The test reports a good connection but on the choose your database objects returns AndreyR's same error.

Only difference is I'm using 5.5 of mysql server.

I notice that the connection string also doesn't include the password in the wizard window even if the Yes,sensitive data button is checked.

metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=Devart.Data.MySql;provider connection string="User Id=rooty;Host=188.169.4.224;Database=reportexec;Persist Security Info=True"

Thank you for the report, this problem is already fixed for all server versions.
The new build will be available in a week or two.
