HttpWebRequest vs. web reference

P: n/a
cj
I'm trying to understand the difference between sites like Google that
offer web references (a .wsdl file) that I can add into my program and
those sites like USPS I have to create a HttpWebRequest to access.

Is the .wsdl file just a way to make it easier for us to user the
services of their sites in our programs?

WSDL file is from a "true" web service. All services must have one and it
describes it's methods, paramaters and return types along with location of
the service.

The HttpWebRequest you are speaking about with UPS just means they don't
have true web services (don't get me started). Just a legacy application that
expects certian data and then returns data. Pain to use.
