In your WinForms project, you encountered an issue enabling Entity Framework 6 for your MySql database. The error message indicated that an Entity Framework database provider compatible with your project was not found.

Solution

To resolve this issue, follow these steps:

1. Remove mysql-installer-community-5.7.3.0-m13.msi: This installer is not necessary for EF6.
2. Install the latest mysql-visualstudio-plugin and mysql-connector-net: Ensure you have the latest versions installed.
3. Create a new WinForms project targeting .Net Framework 4.5: This version is required for EF6 compatibility.

4. Install Nuget packages in the following sequence:

   • EntityFramework (version 6.1.0)
   • Mysql.Data
   • Mysql.Data.Entities
   • Mysql.Web

5. Edit App.config:

   • Comment out the tag if present.
   • Add a new tag after the tag.

6. Add ADO.NET Entity Data Model:

   • Right-click the project and navigate to Add -> New Item -> ADO.NET Entity Data Model.

7. Generate Entity Connection String:

   • Connect to your MySql database and generate the connection string.

8. Choose Database Object and Settings:

   • Select the database objects you want to model and skip the Entity Framework version selection.

9. Complete the Wizard:

   • Finish the wizard to generate the EF6 model.

10. Add Reference to MySql.Data.dll, MySql.Data.Entity.EF6.dll, and MySql.Web.dll:

    • Locate the assemblies in the MySQL Connector Net installation directory and add them as references.

By following these steps, you should be able to successfully enable EF6 for MySql in your WinForms application.
