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

That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.
IStructuralComparable arayüzü, ekseriyetle Array ve Tuple kabil done binaları tarafından uygulanır. Bu done mimariları, elemanlarının sıralamasını ve yapısını dikkate alarak mukabillaştırma yapar.

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you kişi define a custom equality comparison for the array or collection.
So, I am apparently wrong bey unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed kaş of values a requirement?
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position birli, or follows another object in the sort order.
The example on MSDN gives part of the answer here; it seems to be useful for C# IStructuralEquatable Kullanımı heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types
