EntityFramework 6 won't work with MySql

Question

I am trying to use my model and create a database from it. When i try to generate a database based on the model i get the following error:

Running transformation: System.InvalidOperationException: The SSDL generated by the activity called 'CsdlToSsdlAndMslActivity' is not valid and has the following errors:
No Entity Framework provider found for the ADO.NET provider with invariant name 'MySql.Data.MySqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

The following contains my App.config if that is of any help:

<?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" />

  </configSections>
  <connectionStrings>
    <add name="SomeDatabase" providerName="MySql.Data.MySqlClient" connectionString="password=user;server=192.168.0.114;uid=hello;database=example;persistsecurityinfo=True;" />
  </connectionStrings>

  </startup>
  <entityFramework codeConfigurationType="MySql.Data.Entity.MySqlEFConfiguration, MySql.Data.Entity.EF6">
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
  <system.data>
    <DbProviderFactories>
      <remove invariant="MySql.Data.MySqlClient" />
      <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
  </system.data>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"></assemblyBinding>
  </runtime>
</configuration>

I know the issue is with the MySql.Data.MySqlClientbased on the error message, but i can't seem to figure out what it wants me to do. I have added MySql.Data, MySql.Data.Entity.EF6 and EntityFramework to the project.

Anyone knows how to fix this issue?

Is your EF code in a different assembly/project to your program's entrypoint? You may need to add an assembly reference to MySq.Data.MySqlClient to your entrypoint project and ensure your App.config content is in the entrypoint project, not just the library project. — Dai
My EF code is in the same project as my program's entrypoint. The App.config is aswell. — darophi

I was facing the same problem before this. I manage to solve it by creating a whole new project.

Go to Manage NuGet Packages, install EntityFramework, MySql.ConnectorNET.Data and MySql.ConnectorNET.Entity.
Use the connection string as shown here <add name="SomeDatabase" providerName="MySql.Data.MySqlClient" connectionString="server=localhost;port=3306;database=example;uid=hello;password=user"/>
Add [DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))] in DbContext class.
