Using MySQL 5 , Simple Membership Provider, ASP.NET MVC4 with Entity Framework 5

I am trying to: use Simple Membership provider based authentication with MySQL using ASP.NET MVC 4 default web application configured to use MySQL using the tutorial given at: http://www.nsilverbullet.net/2012/11/07/6-steps-to-get-entity-framework-5-working-with-mysql-5-5/

and here at ASP.NET MVC 4 EF5 with MySQL

I am using MySQL Connector 6.6.4 with EF 5.0 and Visual Studio 2012 and working with an ASP.NET MVC 4 Internet application template.

The errors i am facing is this:

Server Error in '/' Application.
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '[UserId] FROM [UserProfile] WHERE (UPPER([UserName]) = 'Z')' at line 1

My code is:

I provided an answer on a similar question here: Using Simple Membership Provider with mysql It's based on a article from Fabio Costa I found here: http://fabiocosta.ca/2012/11/24/use-simplemembership-and-oauth-with-any-database-and-datatype/. You basically get the source code, update it to your needs (let it write mysql queries instead of sql) and use that.
