However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

Reference types (read classes) don't benefit kakım much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

IStructuralComparable arayüzü, ekseri Array ve Tuple gibi done kuruluşları tarafından uygulanır. Bu done kuruluşları, elemanlarının sıralamasını ve yapısını dikkate alarak karşılaştırma yapar.

You generic method has a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you yaşama use .Safi tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

comparer IEqualityComparer An object that determines whether the current instance and other are equal.

This is C# IStructuralEquatable nedir very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I birey just compare each of them":

There is no need for an equality operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
