## What it is
Akka.NET is an idiomatic .NET port of the Akka toolkit implementing the actor model for building highly concurrent, distributed, and fault-tolerant applications in C# and F#. It provides local and clustered actors, remoting, persistence with event sourcing, and stream processing on the .NET runtime.

## Use cases
- build concurrent applications without locks or thread management
- create distributed systems with transparent remote actor communication
- implement event sourcing and CQRS with recoverable actor state
- process streaming data and live event streams
- build fault-tolerant self-healing systems with supervisor hierarchies
- scale out applications across a cluster of machines

## When to choose
- you need high-concurrency message-driven systems on .NET
- you want distributed actors with location transparency and clustering
- you need event-sourced, recoverable state in C# or F#
- you're porting Akka/JVM patterns to the .NET ecosystem

## When to avoid
- you need a simple CRUD web app without concurrency challenges
- your team is unwilling to learn the actor model paradigm
- you need first-class support on a non-.NET runtime
- you want a lightweight library rather than a full runtime framework
