I think the pool logic might be broken; you're adding objects which you see to the pool, and if the objects are on the pool then they're considered the same. It will özne if you have two objects of type A with three properties bey shown below:
When testing two instances for equality you have to make an explicit choice of which IEqualityComparer instance to use.
The CompareTo method would be the default way of ordering your User class, perhaps comparing by Name. If you then decided that you wanted to sort a list of User objects by another property, say Age, you could write a class that implemented IComparer instead of altering CompareTo inside User. This would perform the custom sorting, for example:

However you should have some good pre-checks within GetHashCode to avoid unneccessary calls to this slow method.
I'm looking for real world best practices, how other people might have implemented solutions with complex domains.
Where did the pronunciation of the word "kilometer/kilometre" birli "kl OM iter" rather than "KILL o meeter" originate?
operating on different types of classes, even complex types including sub-objects or nested lists. And derece only on simple classes comprising only primitive type properties.
On the other hand, if there are several equally reasonable methods of comparing two Ts for equality, IEqualityComparer would seem more appropriate: This C# IEqualityComparer Nasıl Kullanılır interface is derece meant to be implemented by T itself, but by other "external" classes.
One feature I wish .Safi had which would improve the usefulness of such dictionaries would be a means of requesting the actual key object associated with a given key (so if the dictionary contained the string "WowZo" bey a key, one could look up "wowzo" C# IEqualityComparer nedir and get "WowZo"; unfortunately, the only way to retrieve an actual key object, if TValue doesn't contain a redundant reference to it, is to enumerate the entire collection).
However, choosing the more specific type Giraffe: return value gönül implicitly be cast to a larger type Animal if needed; and a return type of IEnumerable implicitly casts to IEnumerable. And that's the most C# IEqualityComparer nerelerde kullanılıyor used variant interface. I wonder why the more general type was chosen?
If things don't seem to be working (such kakım duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you C# IEqualityComparer nedir have GetHashCode C# IEqualityComparer Temel Özellikleri ve Kullanımı defined (with override keyword).
