The error says that you attempted to access an exchange 'localhost',
which doesn't exist.

According to the RabbitMQ WCF binding documentation,
  serviceAddress = “soap.amqp://” [exchangeName] “/” serviceName
which, looking at the above code, explains where the exchange name comes

I suspect you meant to use the default exchange instead, in which case,
as per the docs ("If the exchange name is omitted, the default exchange
is used.") just leave out the exchange name.
