There is.
Session.Remove(key)deletes the entry (both key & value) from the dictionary whileSession[key] = nullassigns a value (which happens to be null) to a key. After the former call, the key won’t appear in theSession#Keyscollection. But after the latter, the key can still be found in the key collection.
