The objective of this command is to run the Initial_Create migration. In order to get our migrations under way, we can use dotnet ef database update to perform the initial migrations and the so-called history table. The way i’m going to demonstrate how this can be adopted, for what is described as a ‘code-first’ approach to updating the database schema, is by using the dotnet cli.įor me, there are two areas of consideration:ġ) the Initial Creation of the migrations and,Ģ) the ongoing update of migrations with Idempotence, allowing for repeated runs and updates only when required migrations are missing. So, ideally, our objective here is to obtain an artifact which our release pipeline can use. NET Framework equivalent which typically requires the assistance of Package Manager within Visual Studio. In honesty, there is no right/wrong way in this regard but, I will say, that applying EF Core migrations is a lot easier than the fully-blown. Whilst applying a migration itself is not the difficulty, what is the best way of implementing this in your CI/CD Pipeline when it comes to Entity Framework (EF) does require some consideration. The first thing is, you want to be able to prepare your migrations as part of your build process, however, you will ideally prefer to apply these as part of your release pipeline in what would be the most appropriate timing, certainly not on the back of a build.
