If two objects compare kakım equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare as equal, the GetHashCode methods for the two object do hamiş have to return different values.

If you want to implement IEquatable in a class hierarchy you can use the following pattern. It prevents derived (including sibling) classes from being equal.
Does anyone know what happens if you do hamiş implement iequtalable when using generic collections? 2
It is used by the third example as an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. 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.
If two objects compare kakım equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare bey equal, the GetHashCode methods for the two object do derece have to return different values.

When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.
Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may derece give you the correct results in this super simple example:

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 hamiş mutually exclusive.
