EF Core migration: $ARGUMENTS

EF Core migration: $ARGUMENTS

Create (and optionally apply) an EF Core migration named after $ARGUMENTS. Follow AGENTS.md.

Steps

1. Confirm dotnet-ef is available: dotnet ef --version. If missing: dotnet tool install --global dotnet-ef.
2. Find projects: the migrations project is *.Infrastructure.Data.Repositories (holds ApplicationDbContext); the startup project is *.API. Glob to get the real names.
3. Check the model first: ensure the entity has a DbSet<> in ApplicationDbContext and an IEntityTypeConfiguration in Configurations/. A migration over an unconfigured entity is the usual cause of a wrong/empty diff.
4. Add the migration:

   dotnet ef migrations add <Name> -p <Infrastructure.Data.Repositories> -s <API>
   

5. Review the generated Up/Down before applying — confirm it matches the intended schema change and isn't dropping data unexpectedly.
6. Apply when the user wants it (this writes to a database — confirm the target connection string/environment first):

   dotnet ef database update -p <Infrastructure.Data.Repositories> -s <API>
   

Name the migration after the change (Add_Order, Add_Product_Sku), not a version number.
