### Entity Framework commands
Create a migration, inside of the Console project, referring to the Data project:
`dotnet ef migrations add InitialMigration --startup-project ./ --project ../EntityFrameworkCore.Data`
Update the database:
`dotnet ef database update --startup-project ./ --project ../EntityFrameworkCore.Data`
Database-first scaffolding example: *(no need for escape slashes)*
`Scaffold-DbContext 'connection-string' Microsoft.EntityFrameworkCore.SqlServer -ContextDir ScaffoldDbContext -OutputDir ScallfoldModels`
`dotnet ef dbcontext scaffold "connection-string" Microsoft.EntityFrameworkCore.SqlServer --context-dir ScaffoldDbContext --output-dir ScaffoldModels --startup-project ./ --project ..\EntityFrameworkCore.Data\`
Using `-force` parameter to force overrides when scaffolding.

* It lists the models and their database table names.
* It instantiates a database connection during the runtime of the application.
* Allows configurations to be made in code.
The **migrations** provide a version-controlled method to maintain the state of the database.
* It is possible to track when, and by who changes were made.
* In the Up method, it is described which changes should be made.
* in the Down method, it is described which changes should be undone. This allows rollback.
* There is a history table that is kept by default to track migrations.
