TLDR, how do I make it go?

Righteo, straight to it then:

// Connect to the router
using (var link = Link.Connect("{router-host}", "{router-user}", "{router-password}")) {
	// Get list of interfaces
	var ifaces = link.Interfaces.Query();
	foreach (var iface in ifaces) {
		Console.WriteLine(iface.Name);
	}

	// Get ether1's received byte counter
	var ether1 = ifaces.Single(a => a.DefaultName == "ether1");
	Console.WriteLine(ether1.RxByte);

	// Create new static ARP entry
	link.Ip.Arp.Add(new IpArp() {
		MacAddress = "01:02:03:04:05:06",
		Address = "1.2.3.4",
		Interface = ether1.Name,
		Comment = "Demo ARP entry"
	});
 
	// Ping address
	if (link.Tool.Ping.IsAlive("8.8.8.8")){
		Console.WriteLink("Target lives!");
	} else {
		Console.WriteLink("Target has left the house")
	}
}

Summary

TikLink allows you to control MikoTik routers (RouterOS) from .NET applications. Key features:

• Written in .NET Standard 1.3, for maximum compadibility
• We're a national ISP, and we use it and will continue to maintain it
• Fully thread safe
• SSL-API supported, with a CA-signed cert or with a known public-key (SSH style)
• Simple and easy to use
• Ability to support multiple concurrent requests
• Easy to add support for extra features that come along

Functionality

Most router functionality has been implemented - but there's a lot of it! We have tested the things that we use regularly, but you luck might vary for a feature we haven't used yet. If you find an issue, either feel free to fix it and send a pull-request, or raise a GitHub issue and we'll probably fix it in the next week. See Functionality for a list of features and testing status.

Getting Started
