However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.
Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals hayat't be overridden and always compares by reference.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do derece fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
This member is an explicit interface member implementation. It yaşama be used only when the Array instance is cast to an IStructuralEquatable interface.
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
GetHashCode does hamiş return unique values for instances that are hamiş equal. However, instances that are equal will always return the same hash code.
