问题
since I've installed mysql connector 6.7.4 and Update 3 for Visual Studio 2012 the MySQL Connector is gone away from the Connection Manager dialog.
It was a working project, so the data source configuration is correct. But when I open my existing *.edmx file I get an error (see the picture below).
I've tried to reinstall the connector with rebooting between each installation step, controlled the GAC but I cannot get the connector working back again.
I believe it is related to the Update 3, as mentioned in the comment of the answer post here: mySQL DataSource on Visual Studio 2012
I'm not able to read Portuguese so I don't know if there is already a solution for this problem.
Does somebody have the same issue or does somebody know a solution?
Best regards Felix

The new version of MySQL installer 5.6.14 contains the support for Visual Studio 2008, 2010 and 2012 and you can get it from here: http://dev.mysql.com/downloads/windows/installer/
The below images show how to install that support since by default is not activated

The answer is very easy...
Starting with version 6.7, Connector/Net will no longer include the MySQL for Visual Studio integration. That functionality is now available in a separate product called MySQL for Visual Studio available using the MySQL Installer for Windows (see http://dev.mysql.com/tech-resources/articles/mysql-installer-for-windows.html).
Reference: MySQL NET Connect 6.7.2 in Visual Studio 2012
Too bad that I did not found any documentation about this on the MySQL Website.
