I’m looking at WCF documentation in the MSDN (http://msdn.microsoft.com/en-us/library/bb332338.aspx), and have come across this wee piece of config:
<endpoint name="basicHttpBinding"
address=""
binding="basicHttpBinding"
contract="QuickReturns.StockTrading.ExchangeService.?
Contracts.ITradeService"/>
Can anyone tell me if the question mark is related to WCF, or if it’s XML attribute line continuation? I haven’t found the answer yet.
The question mark is a typo – it shouldn’t be there as it is not a valid part of type name that is being specified for the contract.
Since namespaces and types cannot begin with a question mark it is impossible that this configuration is correct as this could never be a valid CLR type name:
The question mark is some kind of mistake on MSDN (perhaps they meant to add some sort of character indicating a newline and messed up – I am not sure). You can safely remove it and carry on.
