What problem does it solve?

This Skill helps developers choose the most appropriate concurrency abstraction in .NET, guiding them from simple async/await to complex actor models, thereby preventing common concurrency bugs and improving application performance.

Core Features & Use Cases

• Guidance on Abstraction Choice: Provides a decision tree to select between async/await, Parallel.ForEachAsync, Channels, Reactive Extensions, and Akka.NET.
• Synchronization Primitive Deep Dive: Explains the correct usage of lock, SemaphoreSlim, Interlocked, and concurrent collections.
• Anti-Pattern Identification: Highlights common mistakes like blocking on async code or using locks inappropriately.
• Use Case: A developer is building a high-throughput web service and needs to process incoming requests concurrently without blocking. This Skill helps them decide whether to use Channels for a work queue or Akka.NET actors for stateful entity management.

Quick Start

Use the csharp-concurrency-patterns skill to understand when to use Channels for producer/consumer patterns.
