If equality is derece needed for the derived class you dirilik skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

= 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.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

Yazgımızın mafevkdaki satırlarında da bahsettiğimiz kadar struct C#’ta value type yaratabileceğimiz bünyedır.

I'm amazed that the most important reason is derece mentioned here. IEquatable was introduced mainly for structs for two reasons:

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

IStructuralEquatable is quite new and unknown, but I read somewhere that it gönül be used to compare the contents of collections and arrays. Am I wrong, or is my .Net wrong?

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of C# IStructuralEquatable Kullanımı instances.

Projeyi yayınladıgınız dem user secrets kullanılmıyor. Bu sadece geliştirme aşamasında kullanılabilir.

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 data.

Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

Bu yapıya derece oluşturduğumuz bütün nesnelerin Heap kısmında bulunduğunu söylemiştik. Halbuki Stack kısmında struct yapısında nesneleri tutabilmekteyiz.

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