You would need a mapping provider for MySQL  That is an extra thing the Entity Framework needs to make the magic happen  This blog talks about other mapping providers besides the one Microsoft is supplying  I haven t found any mentionings of MySQL

Vintana   Od course there s something ready now  http   www devart com products html - it s commercial although  you have a 30days trial IIRC   They make a living writing providers  so I guess it should be fast and stable  I know really big companies using their Oracle provider instead of Orace and MS ones

It s been released - Get the MySQL connector for  Net v6 5 - this has support for      Entity Framework   I was waiting for this the whole time  although the support is basic  works for most basic scenarios of db interaction  It also has basic Visual Studio integration   UPDATE http   dev mysql com downloads connector net  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
