Should I add a service reference or a web reference?

Service reference is backwards compatible with web reference (service reference being the new, 2008/2010 WCF proxy way of consuming a service).

You should have a WSDL file that defines the web service. If that URL generates a WSDL file (you can try going to the URL in a web browser) then it can be used to generate the service reference. You should definitely use the WCF framework for any web service related programming in .

Net 3.0 onwards. So I would say that use a service reference. WCF is a more customisable, interoperable and peforming framework and is in fact the base for all other distributed computing initiative from Microsoft in recent times (like OData, RIA services etc.).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
