Avoid common C# mistakes — null traps, async pitfalls, LINQ gotchas, and disposal leaks.
Avoid common C# mistakes — null traps, async pitfalls, LINQ gotchas, and disposal leaks.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

?. and ?? prevent NRE but ! overrides warnings — still crashes if null .Result or .Wait() on UI thread — deadlock, use await or ConfigureAwait(false) LINQ is lazy — query.Where(...) doesn't execute until iteration Multiple enumeration of IEnumerable — may re-query database, call .ToList() first Closure captures variable, not value — loop variable in lambda captures last value Struct in async method — copied, modifications lost after await String comparison culture — StringComparison.Ordinal for code, CurrentCulture for UI GetHashCode() must be stable — mutable fields break dictionary lookup Modifying collection while iterating — throws, use .ToList() to iterate copy decimal for money — float/double have precision loss readonly struct prevents defensive copies — use for performance sealed prevents inheritance — enables devirtualization optimization
