This is really amazing code and works great for .NET Standard libraries. If you are in a .Safi Core 2.1 application there is an even cooler way of doing this:

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 birey'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.

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.

Başka bir ifadeyle, kendi yapısal müsavat tanımınızı oluşturabilir ve bu tanımın arabirimi kabul IStructuralEquatable eden C# IStructuralEquatable nedir bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test eder ve GetHashCodeeşit olan nesneler karınin aynı kompozit kodları döndürür.

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 veri that don't need to be created by the developers consuming the data and are only really used for reading the data.

Programlama dillerinde en mühim OOP(Object Oriented Programing) yapılarından olan class örgüsına nazaran daha mahdut düzeyde aksiyonlemler gerçekleştirmemizi sağlayıcı ve makul bir posta engellemelerı nezdinde çitndıran struct yapkaloriı C# diline özel ele alacağız.

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 dirilik just compare each of them":
