To prevent deadlocks in C# async await, avoid blocking on asynchronous operations and follow the "async all the way" principle. This Skill provides guidance on proper Task execution and ConfigureAwait usage to ensure responsive code.

The correct way to use CancellationToken in .NET async methods is through proper token propagation. This Skill covers implementing effective cancellation patterns to handle requests gracefully and avoid unhandled exceptions.

You should use ValueTask instead of Task in C# asynchronous programming when optimizing for performance to reduce allocations. This Skill explains proper Task and ValueTask usage alongside async await best practices.

You can run parallel async operations using Task.WhenAll and Parallel.ForEachAsync to execute multiple tasks concurrently. This Skill details these parallel execution patterns for efficient asynchronous processing in .NET.

You should avoid async void in C# because it causes unhandled exceptions and cannot be awaited. This Skill helps developers understand and fix common AI agent pitfalls like incorrect async void usage and blocking on async operations.
