Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.

In certain scenarios (such bey using the value type kakım a key in a dictionary) it dirilik murder performance in one foul swoop.

. The best example of this is arrays, which with .Safi 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:

Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2

As an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

Your concern is that Object.GetHashCode() does not provide values that are stable and the concern is very valid as güç be seen in the first box headed by Caution in the documentation:

1 My understanding is that it's used for collection C# IStructuralEquatable Temel Özellikleri like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm hamiş really sure if I really got it.

This is 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...

There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.
