I have released a new serializer called MemoryPack, a new C#-specific serializer that performs much faster than other serializers. Compared to MessagePack for C#, a fast binary serializer, the performance is several times faster for standard objects, and even 50~100 times faster when the data is optimal. The best support…

One important use of async/await is proper cancellation processing. Create a CancellationTokenSource, pass a CancellationToken, and handle OperationCanceledException. All this, however, faces some difficulties to implement efficiently. Based on a pattern I faced when implementing a high-speed network client called AlterNats, I will show how to write a process for…

Last month, I’ve released new .NET PubSub library for NATS — Cloud Native, Open Source, High-performance Messaging System. GitHub - Cysharp/AlterNats: An alternative high performance NATS client for .NET. An alternative high performance NATS client for .NET. Zero Allocation and Zero Copy Architecture to achive x2~4…github.com AlterNats is more than three times faster than the official existing clients and five times faster than PubSub on StackExchange.Redis, and all the usual PubSub methods are zero-allocation.

I’ve released a new library called DFrame. https://github.com/Cysharp/DFrame/ DFrame.Controller, which is the real-time web UI, and DFrame.Worker, which writes the load test scenario in C#. Deploying DFrame.Worker in a cluster on the web, with one to thousands of workers working to generate a large number of requests. The ability to…

Minimal API in ASP .NET Core 6 is a one of great feature of .NET 6. This API, which takes full advantage of the power of C# 10.0, has made it very easy to create WebApplications while maintaining a high level of extensibility. However, parsing with System.CommandLine …

There is one major limitation in C# when dealing with arrays, especially byte[]. The upper limit of a one-dimensional array is 0x7FFFFFC7 (2,147,483,591), which is a bit smaller than int.MaxValue. This limitation is different with .NET 6 and other target frameworks. We will discuss it in detail later. This value…

google/zx provides wonrderful solution to write shell script, it keeps the simple writing experience of shell, however fully experience of JavaScript and async/await. I wanted to reproduce it in C#. …

Last month, I’ve released a new library called MessagePipe. GitHub — Cysharp/MessagePipe It mainly supports Publish/Subscribe patterns in in-memory, and covers all cases with a unified interface. For example, it supports communication between different hubs in MagicOnion and SignalR for real-time communication, messenger pattern for loosely coupling between V-VM in…

We released MagicOnion v4 from Cysharp last week. https://github.com/Cysharp/MagicOnion/ MagicOnion has been built on the design principles of C# as Schema, Code-First Contracts for four years, immediately following the release of gRPC 1.0. Until now, we have been using gRPC C Core from Google, and now we are using the…
