    IHydroNetwork network = new Network();

    INode node1 = new Node();
    INode node2 = new Node();
    INode node3 = new Node();

    network.Nodes.Add(node1);
    network.Nodes.Add(node2);
    network.Nodes.Add(node3);

    IChannel channel1 = new Channel { Name = "channel2", Length = 100.0, Source = node1, Target = node2 };
    IChannel channel2 = new Channel { Name = "channel2", Length = 100.0, Source = node2, Target = node3 };

    network.Channels.Add(channel1);
    network.Channels.Add(channel2);

    // add first cross-section directly to branch
    ICrossSection crossSection1 = new CrossSection { Name = "cross-section1", Offset = 50.0 };
    branch1.CrossSections.Add(crossSection1);

    // add second cross-section via network (performance will be smaller!)
    ICrossSection crossSection2 = new CrossSection { Name = "cross-section2", Offset = 50.0, Branch = branch2 };
    network.CrossSections.Add(crossSection2);

Note, that IChannel is an interface extending IBranch from GeoAPI.Extensions.Networks.

You can also use var instead of IChannel, INode types in the code above, to make it a bit simpler:

    var network = new Network();

    var node1 = new Node();
    var node2 = new Node();
    var node3 = new Node();

    network.Nodes.Add(node1);
    network.Nodes.Add(node2);
    network.Nodes.Add(node3);

    var channel1 = new Channel { Name = "channel2", Length = 100.0, Source = node1, Target = node2 };
    var channel2 = new Channel { Name = "channel2", Length = 100.0, Source = node2, Target = node3 };

    network.Channels.Add(channel1);
    network.Channels.Add(channel2);

    // add first cross-section directly to branch
    var crossSection1 = new CrossSection { Name = "cross-section1", Offset = 50.0 };
    branch1.CrossSections.Add(crossSection1);

    // add second cross-section via network (performance will be smaller!)
    var crossSection2 = new CrossSection { Name = "cross-section2", Offset = 50.0, Branch = branch2 };
    network.CrossSections.Add(crossSection2);

All features which are created in the code must be added to the network either directly to the branch or via network.
