I am excited to announce the release of the PrivateProxy library. In essence, it is a library that provides access to private fields/properties/methods. By leveraging the new UnsafeAccessor feature in .NET 8, it achieves No Reflection, high performance, and is AOT-safe. GitHub — Cysharp/PrivateProxy Note: It exclusively runs on .NET…

I recently spoke at CEDEC 2023, the largest game developer conference in Japan. The topic of my talk was about C# performance, drawing on my past implementations and experience, particularly with high-performance serializers like MessagePack for C# and MemoryPack. …

Cysharp has released a communication network client mainly for Unity, supporting HTTP/2, gRPC, and MagicOnion. github — Cysharp/YetAnotherHttpHandler There are two gRPC implementations for .NET: Grpc.Core (C-Core), the native binding of gRPC that Google has been offering, and grpc-dotnet, the Pure C# implementation provided by Microsoft. Currently, .NET’s gRPC is…

I’m excited to announce the release of a new library, MagicPhysX! It’s a physics engine designed for use with .NET, and as its name suggests, it serves as a C# binding for NVIDIA PhysX. GitHub — Cysharp/MagicPhysX Potential applications include: 3D aspects of GUI applications Incorporating a physics engine into…

I have created and released a library that automatically generates C# DllImport code from Rust’s FFI to transparently connect native code and C#. This allows for native code to be smoothly called from C#. Cysharp/csbindgen crates.io/crates/csbindgen First of all, it is important to consider that you should make an effort…

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…
