Why is ConfigureAwait(false) important in library code?

It prevents the task from capturing the original synchronization context, which helps avoid deadlocks and reduces overhead in library-level code.

Does this skill support C# async streams?

Yes, it provides comprehensive patterns for IAsyncEnumerable and the 'await foreach' syntax to handle streaming data efficiently.

When should I use ValueTask instead of Task in C#?

Use ValueTask when an operation is likely to complete synchronously or is called so frequently that the overhead of Task heap allocations impacts performance.

Can Claude help me debug async deadlocks with this skill?

Yes, the skill includes best practices and implementation patterns specifically designed to identify and resolve common asynchronous deadlock scenarios in .NET.

Implements high-performance C# asynchronous programming patterns using Task, ValueTask, and async streams to build responsive applications.

概要

This skill equips Claude with the expertise to architect and implement robust asynchronous C# code. It provides patterns for efficient I/O and CPU-bound operations, covers advanced concepts like ValueTask for performance optimization, ensures thread safety via ConfigureAwait, and handles complex data flows with IAsyncEnumerable streams. It is ideal for developers building scalable web APIs, responsive desktop apps, or high-throughput data processing systems following ethical and professional development standards.
