Note: dotnet EF command

dotnet (. NET Core) is a cross-platform implementation of. NET. You can learn about it here.
dotnet EF Migrations Add Initial runs the Entity Framework. NET Core CLI Migration command and creates an initialization migration. The parameter "Initial" can be any value, but this is usually used as the first (initial) database migration. This action creates a *data/migrations/_initial.cs* file that contains the migration command to add (or delete) the Movie table to the database.
dotnet EF Database Update dotnet EF DB update updates the databases with the migration we just created.
