⚡ CoreSystem.Memory

Lightweight in-memory synchronization library for .NET 8, 9 and 10

CoreSystem.Memory provides keyed asynchronous locks for coordinating concurrent operations within a single process. It is lightweight, thread-safe, dependency injection friendly, and designed for production workloads.

NuGet Downloads License .NET

✨ Features

  • ✅ Keyed asynchronous locking
  • ✅ Thread-safe implementation
  • ✅ Automatic lock lifecycle management
  • ✅ Lightweight and allocation-friendly
  • ✅ Dependency Injection integration
  • ✅ Targets .NET 8, .NET 9 and .NET 10
  • ✅ Production-ready

📦 Installation

dotnet add package CoreSystem.Memory

🚀 Quick Start

Register the services:

builder.Services.AddCoreMemory();

Inject the lock provider:

public sealed class OrderService(IAsyncKeyLock lockProvider)
{
}

Acquire a keyed lock:

await using (await lockProvider.AcquireAsync($"orders:{orderId}"))
{
    // Critical section
}

🏗 Typical Use Cases

  • Prevent concurrent processing of the same entity.
  • Protect critical sections inside ASP.NET Core applications.
  • Synchronize background jobs.
  • Avoid duplicate in-process operations.
  • Coordinate access to shared resources.

⚙️ Configuration

Locks are created on demand with production-ready defaults; there is nothing to configure. Inject IAsyncKeyLock and acquire by key.

📖 Documentation

  • Getting Started
  • Dependency Injection
  • Typical use cases
  • Design
  • Important limitations

Visit the GitHub repository for the complete documentation.

📚 Design

Each key has its own asynchronous lock backed by SemaphoreSlim. Locks are created on demand and automatically removed when no longer in use, preventing unnecessary memory growth.

⚠️ Important

CoreSystem.Memory synchronizes execution only inside the current process.

For synchronization across multiple application instances or servers, use a distributed locking solution such as Redis.
