With WCF 4, the runtime will automatically adds one or more "default endpoints" for you, thereby making the service usable without any configuration, as for this, check this article:
http://msdn.microsoft.com/en-us/library/ee354381.aspx. The default messageEncoding is Text and transferMode is Buffered for the BasicHttpBinding, If you want to change messageEncoding and transferMode,
you need to set the maxBufferSize, MaxReceivedMessageSize and other properties appropriately.
