title: Unique indexes couldn't be exported to database by entity framework
body: <p>I modeled a database with primary keys, foreign keys and unique indexes by using MySQL Workbench. I synchronized my model file with MySQL database and then created a console project in Visual Studio 2012. After that, i added a data entity model with an existing database. There is no problem. To understand if does entity framework create database successfully, i deleted the database. Then i ran the console program, database created successfully but unique indexes couldn't be exported to db. How can i solve this problem?</p>
