What is Akka.NET?

Akka.NET is a free, open-source toolkit for building concurrent, distributed, and fault-tolerant applications on the .NET platform. It's a port of the popular Akka framework from the Java/Scala ecosystem. Akka.NET uses the Actor Model, which provides a higher level of abstraction for dealing with concurrency and parallelism, making it easier to build scalable and resilient systems. It's commonly used in scenarios like building real-time applications, handling high-throughput data processing, and creating distributed systems where fault tolerance is critical.
