To get an idea of the networking features in WP7, I was going to create a simple ping application that would map the result of an ICing ping request to a specific host.
However, not only is the class System.Net.NetworkInformation.Pingmissing, the namespace is System.Net.Socketsalso missing.
After a short study, it turned out that in WP7 there are only two communication methods: a class WebClientthat works with http (s) requests and a WCF client that works with SOA services.
Does this mean that I can not ping hosts directly from the phone? The only possible solution that I see is to implement a separate WCF service on a dedicated server that will ping for the phone, which looks like it is overkill and has certain disadvantages.
