Also it is unclear why GetHashCode takes only value properties into account. Even though it will definitely work but looks a little bit strange. Maybe you should add a comment why class properties

The inclusion of your comparison class (or more specifically the AsEnumerable call you needed to use to get it to work) meant that the sorting logic went from being based on the database server to being on the database client (your application).

That means that your BaseClassComparer constrains the result type to base class and the conversion at the assignment is hamiş possible.

next, when we iterate over the query object it gets hash code for each item in the source collection and compares it with the hashes of preceding objects

This interface allows the implementation of customized equality comparison for collections. That is, you birey create your own definition of equality, and specify that this definition be used with a collection type that accepts the IEqualityComparer interface.

However, like C# IEqualityComparer Temel Özellikleri ve Kullanımı you said in the conclusion, you can achieve the same result with an expression like that:

Bu özellik, engelli kullanıcılar bağırsakin C# IEqualityComparer Nasıl Kullanılır görüntülük okuyucu nominalmlar yahut diğer yardımcı teknolojiler aracılığıyla kullanılabilir.

I'm looking for real world best practices, how other people might have implemented solutions with complex domains.

For me it seemed that LINQ simply ignored my equality C# IEqualityComparer nerelerde kullanılıyor comparer and kept doing everything on its own. In fact, we could check this by adding a debug output to C# IEqualityComparer Temel Özellikleri ve Kullanımı Equals method:

Is there a preferred way of testing two instances of T for equality, or are there several equally valid ways?

Yeni bir referans tipi değustalıkkeni oluşturulduğunda, sadece bir referans oluşturulur ve bellekteki done bu referansın gösterdiği yerde saklanır.

It looks like you're forgetting the immutable nature of IEnumerable. None of the LINQ methods actually change the original variable.

It is all very easy when the context is an assignment to a variable of stated type, but what if the variable is C# IEqualityComparer Temel Özellikleri ve Kullanımı var? What if the context is itself in the argument call to a method? Now we have to do overload resolution problems on that method in order to figure out which one compiles.
