Is there a way to use EntityFramework 4.3 beta with migrations with MySql database? Can we use migrations with MySql Database? Is it possible to use incremental database development with EF code first without me touching the database
Theoretically yes. Practically you first need to get (or create yourselves) class derived from System.Data.Entity.Migrations.Sql.MigrationSqlGenerator which will be responsible for generating SQL for MySQL. Here is more about customizing (or rewriting) SQL generation.
You can also wait until developers of EF supporting ADO.NET providers include this feature to their packages. For example Devart already started work on their migrations support for thier Oracle, MySQL, PostgreSQL and SQLite.
