That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are derece mutually exclusive.
