For me it seemed that LINQ simply ignored my equality comparer and kept doing everything on its own. In fact, we could check this by adding a debug output to Equals method:

Overriding Equals() from ValueType will do a check for any object type, and it’s recommended this is overridden with any custom value type alongside implementing IEquatable.
Basically, using override would mean that you will use your .Equals implementation regardless of whether you are an object C# IEqualityComparer nerelerde kullanılıyor or you are PropertySettings. If you use new when you are an object you will use the base .
And yes, after this the output of the izlence doesn't change at all. So, what the hell is LINQ doing and why doesn't it even try to use the equality comparer that we have provided?
