High-Performance Inter-Process Communication for .NET

NuGet Version Downloads License Build Status codecov

FeaturesGetting StartedDocumentationBenchmarksContributing </div>


🚀 Overview

Selena is a zero-dependency, high-performance C# library for inter-process communication (IPC) using Memory-Mapped Files. It enables real-time message exchange between processes with minimal latency and maximum throughput.

✨ Key Features

  • 🎯 Zero Dependencies - Pure C# implementation, no external libraries required
  • 🌍 Cross-Platform - Works on Windows, Linux, and macOS
  • High Performance - Up to 600+ MB/s throughput with microsecond latency
  • 🔒 Thread-Safe - Built for concurrent multi-threaded scenarios
  • 📦 Multiple .NET Versions - Supports .NET 6/7/8 and .NET Standard 2.0/2.1
  • 🛡️ Type-Safe - Generic message serialization with built-in type safety
  • 🔄 Automatic Recovery - Handles process crashes and reconnections gracefully
  • 📊 Real-Time Monitoring - Built-in performance metrics and diagnostics

📋 Requirements

  • .NET 6.0+ or .NET Standard 2.0/2.1 compatible runtime
  • Windows 7+, Linux (kernel 2.6.22+), or macOS 10.12+
  • Administrator privileges for Global scope (Windows only)

🚀 Getting Started

Installation

Install via NuGet Package Manager:

dotnet add package Selena

Or via Package Manager Console:

Install-Package Selena

Quick Example

using Selena.API;

// Create a channel
using var channel = new SelenaChannel("MyChannel");

// Subscribe to messages
channel.MessageReceived += (sender, e) =>
{
    Console.WriteLine($"Received: {e.GetMessageText()}");
};

// Start listening
channel.Start();

// Send a message
await channel.SendMessageAsync("Hello from Selena!");

Advanced Usage

// Configure advanced options
var config = new SelenaConfig
{
    ChannelName = "AdvancedChannel",
    BufferSize = 10 * 1024 * 1024,  // 10MB buffer
    OverflowStrategy = OverflowStrategy.Overwrite,
    ScopeMode = ScopeMode.Local,     // No admin required
    PollingInterval = 5,             // 5ms for Linux/macOS
    EnableJsonLogging = true
};

using var channel = new SelenaChannel(config);

// Send typed objects
var order = new Order { Id = 123, Total = 99.99m };
await channel.SendObjectAsync(order, messageType: 1);

// Receive typed objects
channel.MessageReceived += (s, e) =>
{
    if (e.Message.Header.MessageType == 1)
    {
        var receivedOrder = e.GetMessageObject<Order>();
        Console.WriteLine($"Order #{receivedOrder.Id}: ${receivedOrder.Total}");
    }
};

📊 Performance Benchmarks

Benchmarks performed on Intel Core i7-10700K, 32GB RAM, NVMe SSD:

Message Size Messages/sec Throughput Latency (μs)
64 bytes 1,200,000+ 73 MB/s < 1
1 KB 680,000+ 664 MB/s 1-2
4 KB 170,000+ 665 MB/s 5-6
16 KB 42,000+ 656 MB/s 20-25

Comparison with Other IPC Methods

Method Throughput Latency CPU Usage
Selena 600+ MB/s < 25μs Low
Named Pipes 200 MB/s 50μs Medium
TCP Loopback 300 MB/s 100μs High
gRPC (local) 150 MB/s 200μs High

🛠️ Configuration Options

Option Description Default Notes
ChannelName Unique channel identifier Required Must be unique per channel
BufferSize Shared memory size 1 MB Minimum 1 KB
OverflowStrategy Buffer full behavior Overwrite Overwrite or Block
ScopeMode Windows IPC scope Local Local (user) or Global (system)
PollingInterval Unix polling interval 10 ms Lower = more responsive
MaxWaitTime Operation timeout 5000 ms For blocking operations
