Question

I was trying to develop a message chat application for LAN (Windows Store App)
using XAML and C#. So, first of all how can I know, the people who are available in LAN
based on their IP addresses?

Any sample code or idea to achieve this?

Answer 1

You can not rely on multicast using WinRT 🙁

However you have 2 solutions :

1. Using IP broadcast : send your bonjour message to 255.255.255.255
2. Add a server node

Note that solution 1 works only on LAN and may be limited by routers and gateways configurations.
