Why am I getting a \'Connection Error\' with MySql.Data and MySql.Data.Entity?

Connection Error with MySql.Data and MySql.Data.Entity

When attempting to establish a connection between a console application and both MySQL and MS SQL using EntityFramework 6.2, MySql.Data 8.0.11, and MySql.Data.Entity 6.10.7, an error may occur:

Error: Attempt by method 'X.set_DbConnection(System.Data.Common.DbConnection)' to access method 'Y.get_Settings()' failed.

This error is caused by a compatibility issue between MySql.Data 8.0.11 and MySql.Data.Entity 6.10.7. Oracle has renamed the package to MySql.Data.EntityFramework for version 8.x.

Solution:

To resolve this error, follow these steps:

1. Uninstall MySql.Data.Entity.
2. Install MySql.Data.EntityFramework.

By installing the correct version of MySql.Data.EntityFramework, the connection between the application and the databases will be successfully established.
