How to Integrate Entity Framework 6 with MySQL in WinForms Applications using Visual Studio 2013?

Integrating Entity Framework 6 with MySql in WinForms in Visual Studio 2013

Problem Statement:

The original question outlines the challenges faced when trying to enable Entity Framework 6 for MySql in a WinForms application within Microsoft Visual Studio 2013. The issue arises when attempting to add an ADO.NET Entity Data Model, where the "Which version of Entity Framework do you want to use?" option is disabled due to a lack of a compatible database provider.

Solution:

To resolve this issue, the following steps should be followed:

• Uninstall the mysql-installer-community-5.7.3.0-m13.msi (if installed).
• Install the latest versions of mysql-visualstudio-plugin and mysql-connector-net.
• Create a new C# .Net 4.5 Framework WinForms application (or ensure that an existing application targets .Net 4.5).
• Install the following NuGet packages in sequence: EntityFramework, Mysql.Data, Mysql.Data.Entities, and Mysql.Web.
• Comment out the existing entityFramework tag in App.config (if present) and add a new one after the startup tag, as shown in the provided App.config snippets below.
• Add an ADO.NET Entity Data Model using the specified steps in the question.
• At the "Entity Connection string is generated" step, check the "Save entity connection settings in App.Config as" option and click Next.
• Proceed with the "Choose Your Database Object and Settings" step. Note that the "Which version of Entity Framework do you want to use?" option should not appear as only the EntityFramework 6.0 provider should be available.

• Add references to the following DLLs in the project:

  • MySql.Data.dll
  • MySql.Data.Entity.EF6.dll
  • MySql.Web.dll

Additional Notes:

• If faced with a missing assembly error during compilation, ensure that the uninstallation of mysql-installer-community-5.7.3.0-m13.msi has removed any previous Entity Framework providers.
• When prompted to downgrade the EntityFramework package to version 6.0.2 by NuGet, click "Yes to All" to complete the installation.
