Introduction

Entity Framework 6 provides an effective method for accessing databases. This article addresses the issue faced while attempting to integrate Entity Framework 6 with a MySql database server in Microsoft Visual Studio 2013 in a WinForms project and presents a comprehensive solution.

Problem

Upon installing EntityFramework 6.0.2 via NuGet Package Manager and attempting to add an ADO.NET Entity Data Model to the project, users may encounter the following error:

"Your project references the latest version of Entity Framework; however, an Entity Framework database provider compatible with this version could not be found for your data connection."

Solution

The key to resolving this issue lies in utilizing the correct combination of NuGet packages and configuration:

1. Install Essential Packages:

   • Install the latest mysql-visualstudio-plugin and mysql-connector-net.

2. Create New Project:

   • Create a new C# .Net Framework 4.5 WinForms project (for .Net Framework 4.0, see caveat below).

3. Install NuGet Packages:

   • Install the following NuGet packages in sequence:

     • EntityFramework
     • Mysql.Data
     • Mysql.Data.Entities
     • Mysql.Web

4. Edit App.config:

   • If tag entityFramework exists in App.config, comment it out.
   • Insert a new tag entityFramework after tag startup.

5. Add Entity Data Model:

   • Follow the steps outlined in the question to add an ADO.NET Entity Data Model.

6. Finalize Configuration:

   • After generating the Entity Connection string, click Next.
   • Choose the database objects to include (tables, views, or stored procedures).
   • Finish the wizard.

Additional Considerations

• For .Net Framework 4.0: Verify its compatibility with Entity Framework 6 based on the information provided in the references.

• Reference DLLs: Add the following DLL files to your project references:

  • MySql.Data.dll
