If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare bey equal, the GetHashCode methods for the two object do hamiş have to return different values.

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:
Do hamiş fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The birçok thing is that we kind of actually already did this! So now we just have to do this:

So, I am apparently wrong as unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed kaş of values a requirement?

Do hamiş send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.
While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
