I understand that trusted silverlight applications can communicate with each other over the LAN

  • 0

I understand that trusted silverlight applications can communicate with each other over the LAN connection (peer to peer). Can they do this without an internet connection once installed out of browser? Do they need to first download some sort of Access Policy?

If not, is there some alternative way of doing this, perhaps with some kind of helper service on the computer?

Can they use similar techniques to talk to Local non-Silverlight devices, e.g. could a trusted silverlight application talk to an iPhone app over a local area network?

    System.Net.Sockets.UdpAnySourceMulticastClient

    Does allow you to connect between Multiple Silverlight applications on the same LAN. It does not require any internet connection after the application is installed out of browser.

    I’m not clear if this could be used for communication with non-Silverlight applications althouh I believe it probably could since UDP Multicast is a standard protocol.

    In situations where the network infrastructure is older it may not support UDP Multicast addresses. In this case, the best solution would be to install a separate local server on one of the client machines, to which all other silverlight applications could connect (once the user had typed in the IP address).
