'string.Contains(string)' has a method overload that takes a 'StringComparison' parameter. Replace this call in 'AdventOfCode.Core.SolutionHandler.GatherPuzzleSolutions()' with a call to 'string.Contains(string, System.StringComparison)' for clarity of intent.

In externally visible method 'char? StringExtensions.Get(string[] map, (int R, int C) pos)', validate parameter 'map' is non-null before using it. If appropriate, throw an ArgumentNullException when the argument is null or add a Code Contract precondition asserting non-null argument.

In externally visible method 'void ListExtensions.Deconstruct<T>(IList<T> list, out T first, out IList<T> rest)', validate parameter 'list' is non-null before using it. If appropriate, throw an ArgumentNullException when the argument is null or add a Code Contract precondition asserting non-null argument.
