## What it is
CQRSlite is a lightweight CQRS and Event Sourcing framework for .NET that provides building blocks like command dispatching, event publishing, repositories, sessions, snapshots, and caching. It is minimal-dependency, pluggable, and targets netstandard2.0 and net9.0.

## Use cases
- build a CQRS application in C#
- implement event sourcing in .NET
- manage aggregates with a unit of work and optimistic concurrency
- add snapshotting to aggregates with many events
- dispatch commands and publish events with automatic handler routing
- learn CQRS/ES patterns in a small codebase

## When to choose
- you want a minimal, pluggable CQRS/ES foundation rather than a heavyweight framework
- you are on .NET and want few dependencies
- you need snapshots, caching, and concurrency checking out of the box

## When to avoid
- you need a full-featured framework with built-in event store, projections, or messaging transport
- you are not using .NET/C#
- you want turnkey infrastructure instead of assembling your own components

## Facets
- artifact type: framework
- maturity: active
- function: middleware, message-queue, caching, serialization
- domain: backend, developer-tools, microservices, apis
- platform: dotnet, cross-platform, serverless
- tags: cqrs, event-sourcing, ddd, aggregate-roots, netstandard, command-handling, event-bus, snapshots, optimistic-concurrency, unit-of-work
