How to Integrate MySQL with Entity Framework 4 and Code-First Development?

Integrating MySQL with Entity Framework 4 and Code-First Development

In the realm of database development, Entity Framework (EF) 4 has gained prominence as a powerful ORM framework. Utilizing Microsoft's ASP.NET MVC 2, a developer sought to harness the code-first approach with EF4, leveraging the ubiquitous MySql database instead of Sql Server.

Upon encountering a ProviderIncompatibleException, the developer delved into the intricacies of the configuration. Notably, two fundamental observations emerged:

  • Pre-existing Database Requirement: Unlike Sql Server, MySql prohibits automatic database creation; hence, it must already exist.
  • ConnectionString Naming Convention: Each database context necessitates a distinct connection string bearing its name.

Furthermore, the developer ascertained that the table name within MySql corresponded to the DbSet name employed in the context definition. Acceding to these nuances paved the way for successful implementation.

Post-Deployment Considerations for MySql

During deployment, however, the developer encountered a data factory incompatibility that hindered the application's functionality. Resolving this issue involved adding a DataFactory to the web.config, as follows:

<system.data>
  <DbProviderFactories> 
    <add name="MySQL Data Provider"
         invariant="MySql.Data.MySqlClient" 
         description=".Net Framework Data Provider for MySQL"
         // Ensuring compatibility with the deployed MySQL DLL
         type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.3.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> 
  </DbProviderFactories> 
</system.data>

By adhering to these guidelines and incorporating the DataFactory, the integration of MySQL with EF4 and code-first development became a reality.
