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

ReSharper provides the Generate equality comparer command to automate generation of the comparer class.

This is it. We have explored the interaction between LINQ extension methods and custom IEqualityComparers and even implemented one. The resulting class is both easy to use and highly customizable, because its operation is fully defined by the key selector function provided by user.

If there is only one way of testing two instances of T for equality, or if one of several methods is preferred, then IEquatable would be the right choice: This interface is supposed to be implemented only by T itself, so that one instance of T katışıksız internal knowledge of how to compare itself to another instance of T.

The IEqualityComparer interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the IComparer interface.

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" birli a key, one could look up "wowzo" 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).

Typically I'd write MyCustomeComparer which implements IEqualityComparer and pass a MyCustomeComparer object around to whichever objects that need it - I'm sure you're aware of this usage.

Birli we saw above, it doesn’t take much code. Kakım our örnek evolves, we’ll likely have to extend our comparers, so always thinking about what “equal” means now and what it could mean in the future is a valuable exercise.
