Gitter

Akka.NET is a .NET port of the popular Akka project from the Scala / Java community. We are an idiomatic .NET implementation of the actor model built on top of the .NET Common Language Runtime.

Akka.NET is a .NET Foundation project.

How is Akka.NET Used?

Akka.NET can be used in-process or inside large, distributed real-time systems; we support a wide variety of use cases.

Akka.NET can be used to solve the following types of problems:

  1. Concurrency - Akka.NET actors only process messages one-at-a-time and they do so in first in, first out (FIFO) order; this means that any application state internal to an actor is automatically thread-safe without having to use locks or any other shared-memory synchronization mechanisms.
  2. Stream Processing - Akka.NET actors and Akka.Streams make it easy to build streaming applications, used for processing incoming streams of data or incoming streams of live events such as UI or network events inside native applications.
  3. Event-Driven Programming - actors make it easy to build event-driven applications, as actors' message-processing routines naturally express these types of designs.
  4. Event Sourcing and CQRS - Akka.Persistence, used by actors to make their state re-entrant and recoverable across restarts or migrations between nodes, natively supports event sourcing. Akka.Persistence.Query can be used to compute CQRS-style projections and materialized views from Akka.Persistence data.
  5. Location Transparency - Akka.Remote makes it simple for actors in remote processes to transparently communicate with each other.
  6. Highly Available, Fault-Tolerant Distributed Systems - Akka.Cluster, Akka.Cluster.Sharding, and other tools built on top of Akka.Cluster make it possible to build highly available and fault-tolerant distributed systems by leveraging peer-to-peer programming models with topology-aware message routing and distribution.
  7. Low Latency, High Throughput - Akka.NET aims to be low latency and high throughput, processing 10s millions of messages per second in-memory and hundreds of thousands of messages per second over remote connections.

Install Akka.NET via NuGet

If you want to include Akka.NET in your project, you can install it directly from NuGet

To install Akka.NET Distributed Actor Framework, run the following command in the Package Manager Console

PM> Install-Package Akka.Hosting

Akka.Hosting includes the base Akka NuGet package and also provides an easy interface to integrate Akka.NET with the most-used parts of the Microsoft.Extensions ecosystem: Configuration, Logging, Hosting, and DependencyInjection. We encourage developers to adopt it.

And if you need F# support:

PM> Install-Package Akka.FSharp

Akka.NET Project Templates

To create your own Akka.NET projects using our templates (Akka.Templates), install them via the dotnet CLI:

dotnet new install "Akka.Templates::*"

This will make our templates available via dotnet new on the CLI and as new project templates inside any .NET IDE such as Visual Studio or JetBrains Rider. You can view the full list of templates included in our package here: https://github.com/akkadotnet/akkadotnet-templates#available-templates

Akka.NET v1.5.9 is a maintenance release that introduces some performance improvements and internal code cleanup/modernization. __Changes:__ [Remoting: Make transport adapter component public](https://github.com/akkadotnet/akka.net/pull/6838) __Improvements:__ [Memory optimization, use `Array.Empty` instead of creating empty arrays](https://github.com/akkadotnet/akka.net/pull/6801) [Remoting: Log all wrapped message layers during errors](https://github.com/akkadotnet/akka.net/pull/6818) [Port #6805 and #6807, Improve Stream and Pattern.Backoff instance creation time performance](https://github.com/akkadotnet/akka.net/pull/6821) [DData: Harden LWWDictionary serialization null check](https://github.com/akkadotnet/akka.net/pull/6837) __Code modernization:__ [Use C# 9.0 target-typed new()](https://github.com/akkadotnet/akka.net/pull/6798) [Use C# 8.0 null-coalescing operator](https://github.com/akkadotnet/akka.net/pull/6814) __Update dependency versions:__ [Bump Google.Protobuf to 3.23.4](https://github.com/akkadotnet/akka.net/pull/6826) [Bump Akka.MultiNode.TestAdapter to 1.5.8](https://github.com/akkadotnet/akka.net/pull/6802) [Bump Microsoft.Data.SQLite to 7.0.9](https://github.com/akkadotnet/akka.net/pull/6835) [Bump Microsoft.Extensions.ObjectPool to 7.0.8](https://github.com/akkadotnet/akka.net/pull/6813) [Bump Xunit to 2.5.0](https://github.com/akkadotnet/akka.net/pull/6825) __Akka.TestKit.Xunit Changes__ Due to breaking API change in Xunit 2.5.0, updating to Akka.NET 1.5.9 might break your unit tests. Some of the breaking change that we've noticed are: `AkkaEqualException` constructor has been changed due to changes in Xunit API. If you're using this class, please use the `AkkaEqualException.ForMismatchedValues()` static method instead of using the constructor. Testing for exception types by calling async code inside a sync delegate will not unwrap the `AggregateException` thrown. Either use async all the way or manually unwrap the exception. Xunit `Asset.Equal()` does not automatically check for collection item equality anymore, that means doing `Assert.Equal()` between two dictionary or list would not work anymore. Some Xunit classes have been changed from public to private. If you're using these classes, you will need to refactor your code. __FsCheck.Xunit:__ Xunit Roslyn analyzer has become a bit too overzealous and insists that all unit test method can only return either void or Task and will raise a compilation error if you tried to return anything else. If you're using `FsCheck.Xunit`, you will need to use a pragma to disable this check: `#pragma warning disable xUnit1028`.
