I need to write a wcf service that accepts 3rd party applications to send a xml file to the wcf service.An example of a xml file could be:\[code\]<?xml version="1.0" standalone="yes"?><Customers> <Customer> <ID>1</ID> <Name>Name 1</Name> </Customer> <Customer> <ID>3</ID> <Name>Name 3</Name> </Customer></Customers>\[/code\]How do I setup the wcf service to accept this collection of data?
