What is the use of the ArraySegment class?
... and WCF liking it. Which is probably the proper guidance, if you like it then use it. It did do a peek-a-boo in .NET 4.6, the added MemoryStream.TryGetBuffer() method uses it. Preferred over having two out arguments I assume.

After all, who would prefer @subdomain.domain...

... finding out whether a variable has been declared regardless of its value, then using the in operator is the safest way to go. Consider this example:
