- Made Array.IndexOf available via extension method. - Made ToHashSet extension method. - Change collections queried often via Contains into sets. - Avoid Count() extension if Count or Length property exist. - Made Count() > 0 checks and variations calls to Any() instead. - Don't call ToList/ToArray if there is no benefit to materializing the sequence. - If the sequence does benefit from materialization, follow this general pattern: - Collection queried often via Contains use ToHashSet to speed up lookups. - Short lived variables use ToList. This is because ToArray requires an extra copy to output the final size. - Collections persisted into fields or for a long time use ToArray to minimize memory overhead.
