What projects make up Its.Cqrs?

Its.Domain

This project contains a number of core abstractions for building an event-sourced domain model, including:

• aggregates, events, and commands
• rule-based command validation
• rule-based command authorization
• event handling
• command scheduling, with durability and retries
• building projections from events
• controlling time
• avoiding primitive obsession in the domain
• reserving values for uniqueness checks or ticket pools

Its.Domain.Api

This project allows you to expose your domain commands by convention via ASP.NET Web Api.

Its.Domain.Sql

This project provides Microsoft SQL Server-backed implementations for an event store, read model databases, command scheduler, and reservation service. It also supports building projections based on your event store.

Its.Domain.Testing

This project provides a number of tools for testing your domain, including virtual clocks, in-memory repositories, and in-memory command scheduling.
