What C# versions does this skill support?

This skill covers modern C# asynchronous patterns introduced and refined in versions 8 through 12.

Does it help with performance optimization?

Yes, it provides specific guidance on using ValueTask to reduce heap allocations and using ConfigureAwait(false) to optimize context switching in library code.

Can it help fix 'async void' issues?

Absolutely. The skill includes patterns to identify and replace dangerous async void methods with Task-based logic to ensure proper exception handling.

Does it support streaming large datasets?

Yes, it includes implementation patterns for IAsyncEnumerable and async streams to process data items asynchronously as they become available.

API Development

Implements high-performance, scalable C# asynchronous programming patterns using modern async/await, Task, and ValueTask standards.

This skill equips Claude with specialized knowledge of C# asynchronous programming, ranging from basic async/await fundamentals to advanced patterns like async streams and cancellation tokens. It helps developers write non-blocking, responsive code by providing domain-specific guidance on performance optimizations such as ValueTask, the proper application of ConfigureAwait(false) in library code, and avoiding common pitfalls like async void. It is particularly useful for building scalable backend services, responsive UI applications, and resource-efficient library components using C# 8-12.
