    • IsDistinct(By) : Check if the collection doesn't contains duplicate element
    • IsInOrder(By) : Check if the elements in collection is in order
    • MinMax(By) : Get minimun value and maximun value in one iteration
  • Creation
    • EnumerateByWhile/NotNull : Yield next value selected by a Func<T, T>, until predicate failed
    • EnumerateDescendantsDepth/BreadthFirst : Traverse tree
  • Element
    • TryAt : TryXXX version of ElementAt
    • TryFirst : TryXXX version of First
    • TryLast : TryXXX version of Last
    • FirstNearToMax(By)(OrDefault) : Find the first item has priority greater than given priority, if not found, return the first item with greatest priority
    • TrySingle : Returning tagged union version of Single
  • Filtering
    • Duplicates : Return all elements that is not distinct in collection
    • OfNotNull : Filter out all null values
    • TakeEvery : Yield the values in specific interval
  • Joining

  • ToCollections
    • ForEach
    • EmptyIfNull : Return empty collection if source collection is null
