About MagicOnion

2025년 1월 27일 최종 업데이트

MagicOnion is a modern RPC framework for .NET platform that provides bi-directional real-time communications such as SignalR and Socket.io and RPC mechanisms such as WCF and web-based APIs.

This framework is based on gRPC, which is a fast and compact binary network transport for HTTP/2. However, unlike plain gRPC, it treats C# interfaces as a protocol schema, enabling seamless code sharing between C# projects without .proto (Protocol Buffers IDL).

Interfaces are schemas and provide API services, just like the plain C# code

Using the StreamingHub real-time communication service, the server can broadcast data to multiple clients

MagicOnion can be adopted or replaced in the following use cases:

• RPC services such as gRPC, used by Microservices, and WCF, commonly used by WinForms/WPF
• API services such as ASP.NET Core MVC targeting Unity, Xamarin, and Windows clients
• Bi-directional real-time communication such as Socket.io, SignalR, Photon and UNet

MagicOnion uses MessagePack for C# to serialize call arguments and return values. NET primitives and other complex types that can be serialized into MessagePack objects. See MessagePack for C# for details about serialization.
