Entity Framework 6 with MySQL - Class Library - mysql

Question

I have a project in visual studio (web MVC app) linked to a MySQL database with EF6. Everything is working, I have the provider referenced on web.config, everything is correct. Now I want to separate the Data access to a new project of type class library. I created the project, added the references (MySql.Data and MySql.Data.Entity.EF6), added the provider to the app.config, I think I did all the steps, but I'm stuck when I try to create a new data context with the error below.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

<add name="DefaultConnection" connectionString="metadata=res://*/Models.teste.csdl|res://*/Models.teste.ssdl|res://*/Models.teste.msl;provider=MySql.Data.MySqlClient;provider connection string="server=###############;user id=#############;password=############;database=###########"" providerName="System.Data.EntityClient" />
</connectionStrings>

<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6"></provider>
</providers>
</entityFramework>
<userSettings>
<dPhotos.data.Properties.Settings>
<setting name="fdsgd" serializeAs="String">

</dPhotos.data.Properties.Settings>

Try this:
On your machine where Visual Studio, MySQL VS plugin and Connector/Net are installed:
close all VS instances before doing the steps.
on a Windows Explorer window go to this path or wherever you installed you Connector/NET binaries:
C:\Program Files (x86)\MySQL\MySQL Connector Net {version}\Assemblies\v4.5\
copy the file MySql.Data.Entity.EF6.dll and paste it to this folder:
C:\Program Files (x86)\Microsoft Visual Studio {version}\Common7\IDE\PrivateAssemblies
(if it asks you to overwrite it please do so. You'll need admin rights in order to overwrite the file.)
add reference to this DLL in the project.
Then you can try again to generate the script for your model.
Your app.config should look like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
