Why am I getting a \'Attempt by method \'MySql.Data.Entity.EFMySqlCommand.set_DbConnection(System.Data.Common.DbConnection)\' to access method \'MySql.Data.MySqlClient.MySqlConnection.get_Setting

EF Entity Framework and MySQL Connection Error

In an effort to create a console application that utilizes EntityFramework 6.2, MySql.Data 8.0.11, and MySql.Data.Entity 6.10.7 for database connections, a persistent error has emerged:

"Attempt by method 'MySql.Data.Entity.EFMySqlCommand.set_DbConnection(System.Data.Common.DbConnection)' to access method 'MySql.Data.MySqlClient.MySqlConnection.get_Settings()' failed."

Resolving the Incompatibility

Upon investigation, it becomes apparent that the root cause of this error lies in the incompatibility between MySql.Data.Entity 6.10.7 and MySql.Data 8.0.11.

Oracle, the developer behind MySQL, has renamed the package from MySql.Data.Entity to MySql.Data.EntityFramework in version 8.x. To rectify the issue, uninstall MySql.Data.Entity and install MySql.Data.EntityFramework instead.

Ensuring Compatibility

To ensure compatibility between your application and the MySQL database, it is essential to use the correct package versions. Reference the latest documentation for MySql.Data.EntityFramework to determine the appropriate version for your project.

This resolution should address the connection error you have encountered, allowing you to proceed with the development of your console application that leverages EntityFramework and MySQL for database operations.
