This project uses .NET Core and EF Core.

In EF Core there isn't an enable-migrations command.

You can use the following commands:

dotnet ef migrations add [Name] -o Data/Migrations
dotnet ef database update

For more info, please refer to the offcial docs: https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/dotnet
