csharp-async SKILL.md skillA
csharp-async from github/awesome-copilot is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add github/awesome-copilot/csharp-async@git:20260224.caab1f6Pins git:20260224.caab1f6 in mdr.lock. Pin the fingerprint instead.

Get best practices for C# async programming.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# C# Async Programming Best Practices Your goal is to help me follow best practices for asynchronous programming in C#. ## Naming Conventions - Use the 'Async' suffix for all async methods - Match method names with their synchronous counterparts when applicable (e.g., `GetDataAsync()` for `GetData()`) ## Return Types - Return `Task<T>` when the method returns a value - Return `Task` when the method doesn't return a value - Consider `ValueTask<T>` for high-performance scenarios to reduce allocations - Avoid returning `void` for async methods except for event handlers ## Exception Handling - Use try/catch blocks around await expressions - Avoid swallowing exceptions in async methods - Use `ConfigureAwait(false)` when appropriate to prevent deadlocks in library code - Propagate exceptions with `Task.FromException()` instead of throwing in async Task returning methods ## Performance - Use `Task.WhenAll()` for parallel execution of multiple tasks - Use `Task.WhenAny()` for implementing timeouts or taking the first completed task - Avoid unnecessary async/await when simply passing through task results - Consider cancellation tokens for long-running operations …

How to install
mdr add github/awesome-copilot/csharp-async@sha256:d52c0812a3e4325aThe line at the top of this page pins the label git:20260224.caab1f6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
