Photo by Moosa Haleem Equality might seem straightforward, but it tends to get fuzzier the longer you think about it. When it comes to programming, there are two general thoughts around equality.
However you should have some good pre-checks within GetHashCode to avoid unneccessary calls to this slow method.

So what happens when it comes time to actually deduce the type argument? We have two candidates: Position and BaseClass. Both satisfy the stated bounds. Position satisfies the first bound because it is identical to the first bound, and satisfies the second bound because it is smaller than the second bound.
– Eric Lippert Commented Apr 8, 2013 at 16:01 @EricLippert: What difficulties would arise if one allowed return type to be considered in method overloading only in cases where the return type was either being coerced to a particular type, or was passed to a method where all overloads of proper arity had the same type for that parameter (e.
When we make the inference from allPositions to IEnumerable we say "IEnumerable C# IEqualityComparer Temel Özellikleri ve Kullanımı is covariant in T, so we sevimli accept Position or any larger type
