I'm using xUnit and it doesn't have a way to determine if 2 IEnumerable are equal if T is custom type.
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).

The first is the idea of precise equality. Given two references to objects, do the two references point to the same location in memory? Programming languages are suited for this kind of comparison, and .Kupkuru comes with many prebuilt operators to handle this case.
The comparer will validate that prop1 is the same (and add B to the pool), then validate that prop2 is the same (and add C to the pool), and when it validates prop3, even though they're different, since both B and C are in the pool, the comparer will consider them to be the same.

I've tried using LINQ SequenceEqual but again bey the instances of T are C# IEqualityComparer nedir different this returns false;
recordが利用可能なケースではできるだけrecord型で定義するようにしましょう。
2 It affects other places in a positive way, you generally want to implement it for a veri class like this
I have to say, that there are other methods to create an equality comparer with similar functionality. For example, see this C# IEqualityComparer Nasıl Kullanılır article on CodeProject - it demonstrates how C# IEqualityComparer Nasıl Kullanılır to use reflection to obtain and compare property values.
I'm glad the post was of some value to you. If you are looking to avoid common C# IEqualityComparer Nasıl Kullanılır problems arising with LINQ, you may also like my post diving into what deferred nature of some LINQ methods means to a programmer: [^]
