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

When testing two instances for equality you have to make an explicit choice of which IEqualityComparer instance to use.

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.

Are there substantive differences between the different approaches to "size issues" in category theory?

Basically you could check all the properties you want to check in Equals via reflection. To filter some of them out use an attribute on those properties:
