I am using Visual Studio 2013 Ultimate and I got it working with the Mysql Visual Studio 1.1.1 beta plugin.
Requirements:
- Windows OS 7 or later.
- Visual Studio 2010, 2012 or 2013 professional or higher version.
- Connector/Net 6.8.1 beta or higher version to check the Connector/Net & Entity Framework features. (download at: http://dev.mysql.com/downloads/connector/net/ on the development releases).
