Troubleshooting Entity Data Model Creation Failure for MySQL and EF6

When attempting to create an Entity Data Model (EDMX) for a MySQL database using Entity Framework 6 (EF6), you may encounter an issue where the EDMX file is not created. This article provides a comprehensive guide to resolving this problem and successfully establishing an Entity Framework connection to your MySQL database.

Troubleshooting Steps

1. Uninstall and Reinstall MySQL Components:

   • Uninstall any existing "Connector/NET" and "MySQL for Visual Studio" installations.
   • Install "MySQL for Visual Studio" v2.0.5 CTP (https://mysql.com/downloads/windows/visualstudio-plugin/).
   • Install "Connector/NET" v6.9.10 (https://dev.mysql.com/downloads/connector/net/).

2. Add EF6 via NuGet:

   • In your Visual Studio project, install "EntityFramework" v6.2.0 via NuGet by browsing "Project Tab » Manage NuGet Packages" and searching for "Entity Framework."

3. Add References to MySQL Assemblies:

   • Add references to the following assemblies:
   • MySql.Data.dll
   • MySql.Data.Entity.EF6.dll
   • Browse to these assemblies at "C:\Program Files (x86)\MySQL\Connector.NET 6.9.10\Assemblies\v4.5\"

4. Configure App.config for MySQL EF6 Provider:

   • Add the following provider information to your App.config file under the "entityFramework" section:

   <entityFramework>
       <providers>
         <provider invariantName="MySql.Data.MySqlClient"
              type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
       </providers>
   </entityFramework>

5. Rebuild Project:

   • Rebuild your project to apply the changes.
