3.26 Changes in MySQL Connector/NET 8.0.12 (2018-07-27, General Availability)

Known Limitation of This Release

To create a model in Entity Framework (EF) Core v2.0 with scaffolding or migration in this release, use the following alternative procedure:

Downgrade to EF Core 1.0 or 1.1 in your project, install the MySql.Data.EntityFrameworkCore.Design NuGet package, and then create your model using the scaffolding or migration command.
With the model created, revert back to EF Core 2.0 in your project, update the MySql.Data.EntityFrameworkCore NuGet package, and then remove the package MySql.Data.EntityFrameworkCore.Design from your project.

We are sorry for this temporary inconvenience.
