What problem does it solve?

This Skill helps you master asynchronous programming in .NET, enabling you to build high-performance, scalable, and responsive ASP.NET Core applications. It addresses common pitfalls like deadlocks, thread pool starvation, and inefficient I/O operations, ensuring your applications remain fluid under load.

Core Features & Use Cases

• Async/Await Fundamentals: Guides on correctly implementing and calling async/await methods, avoiding common blocking patterns that lead to deadlocks.
• ConfigureAwait & ValueTask: Explains the nuances of ConfigureAwait(false) for library code and when to use ValueTask for performance optimization in hot paths.
• Cancellation Tokens: Demonstrates how to integrate CancellationToken throughout your async operations, allowing for graceful termination of long-running tasks.
• Parallel Processing: Patterns for efficiently executing multiple independent async operations concurrently using Task.WhenAll and Task.WhenAny, improving overall application speed.
• Use Case: A backend developer needs to optimize an ASP.NET Core API endpoint that makes multiple external service calls. Using this skill, they refactor the endpoint to use Task.WhenAll to execute calls in parallel and integrate CancellationToken for better responsiveness.

Quick Start

Refactor a synchronous method that calls two independent database operations into an asynchronous method using Task.WhenAll to execute them in parallel.
