Entity Framework Core
Add relational persistence when your Arc application needs it. The optional Cratis.Arc.EntityFrameworkCore package provides context registration, model conversion, and observation without requiring Chronicle or event sourcing. Begin with getting started; registration selects a provider but does not create your schema.

Overview
Section titled “Overview”The Entity Framework Core integration in the Arc streamlines database operations by providing sensible defaults, automatic configuration, and patterns that work well with CQRS architecture. Whether you’re working with read-write or read-only contexts, the framework handles the complexity of setup and configuration while giving you the flexibility to customize when needed.
