## From README

ABP Entity Framework Core Docs: https://abp.io/docs/latest/framework/data/entity-framework-core Never Do | Don't | Do Instead | |-------|-----------| | Skip b.ConfigureByConvention() | Always call it first in entity config | | AddDefaultRepositories(includeAllEntities: true) | Use AddDefaultRepositories() only for aggregate roots | | Inject DbContext in application/domain services | Use IRepository or custom repository interface | | Use DbContext directly outside the EF Core project | Access via GetDbContextAsync() inside repository only | DbContext Configuration Entity Configuration Repository Implementation Extension Method for Include Migration Commands Note: ABP templates include IDesignTimeDbContextFactory in the EF Core project, so -s (startup project) parameter is not needed. Module Configuration Best Practices Repositories for Aggregate Roots Only Don't use includeAllEntities: true in AddDefaultRepositories().
