Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

If you want to implement IEquatable in a class hierarchy you dirilik use the following pattern. It prevents derived (including sibling) classes from being equal.
Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals hayat't be overridden and always compares by reference.
I'm amazed that the most important reason is not mentioned here. IEquatable was introduced mainly for structs for two reasons:

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
şu demek oluyor ki anlayacağınız “int” üzere, “bool” kabilinden kıymet tipli bir değişebilir tevlit etmek istiyorsanız struct yapkaloriı tercih edebilirsiniz.

In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of data that don't need to be created by the developers consuming the data and are only really used for reading the veri.
C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.

You observations does not conflict with the documentation and there is no bug in the implementation.
