Why is MySQL not appearing as an option when connecting to my Entity Framework 6 model?

Troubleshooting MySQL Connection for Entity Framework 6

When attempting to create an ADO.NET Entity model and connect it to a MySQL database, you may encounter an issue where MySQL does not appear as an option for the connection. Despite installing the MySQL plugin for Visual Studio 1.1.1 and MySQL .Net connector 6.8.3, you face this challenge.

Bug in MySQL Connector

This issue is caused by a known bug in the MySQL connector. A workaround involves copying the following DLL from the MySQL Connector Net installation folder:

C:\Program Files (x86)\MySQL\MySQL Connector Net 6.8.3\Assemblies\v4.5\MySql.Data.Entity.EF6.dll

and pasting it into:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies

Ensure youoverwrite the existing file and restart Visual Studio.

Additional Steps for Entity Framework 6

If you encounter further issues after applying the workaround, consider these additional steps:

• Add the following DLLs to your project:

  • MySql.Data.dll
  • MySql.Data.Entity.EF6.dll
  • MySql.Web.dll
• Modify the EntityFramework section in your web.config as follows:

<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" />
    </providers>
  </entityFramework>

• Rebuild your project.

Latest Update

The bug has since been resolved. To use MySQL with Entity Framework 6, install the latest MySQL for Windows installer with Visual Studio support and the latest Connector.Net. Update to the latest versions of each via NuGet.

By following these steps, you can establish a proper connection to a MySQL database using Entity Framework 6. Ensure that you have the correct versions of the necessary components installed for a seamless experience.
