Namespace Tizen.Network.Nsd

The Tizen.Network.Nsd namespace provides classes to manage the network service discovery protocols.

Overview

The Nsd API handles DNS-SD (DNS Service Discovery) protocol. It allows applications to announce local services and search for remote services on a network.

Registering a Service on Network

// Create and register a service
DnssdService service = new DnssdService("_http._tcp");
service.Name = "TestService";
service.Port = "1234";
service.RegisterService();

// Optional: Add TXT records
service.AddTXTRecord("version", "1.0");

Discovering Services on Network

// Create browser and start discovery
DnssdBrowser browser = new DnssdBrowser("_http._tcp");
browser.ServiceFound += (s, e) =>
{
    if (e.State == DnssdServiceState.Available)
    {
        // Handle the discovered service
    }
};
browser.StartDiscovery();

Cleaning Up on Application Exit

// Stop service discovery
browser.StopDiscovery();

// Deregister service and dispose resources
service.DeregisterService();
service.Dispose();
