How to debug step by step managed code with MDbgEngine

Question

Assuming that I have simple C# console application (code below). I want to debug it step by step using mdbg manager wrapper.

using System;

namespace TestApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("1");
            Console.WriteLine("2");
            Console.WriteLine("3");
            Console.WriteLine("4");
            Console.WriteLine("5");
        }
    }
}

How to use MDbgEngine to debug this code step by step?

[MTAThread]
static void Main(string[] args)
{
    var debugger = new MDbgEngine();
    debugger.Options.CreateProcessWithNewConsole = true;
    debugger.Options.StopOnException = true;

    var process = debugger.CreateProcess("TestApplication.exe", "", DebugModeFlag.Debug, null);
    process.Go();

    //HOW TO GO STEP BY STEP TROUGH THE TestApplication?
}

You have to subscribe to process.PostDebugEvent event, Hopefully debugger will stop at very beginning of your application or you can put breakpoint in the location you want using process.Breakpoints.CreateBreakpoint()

process.PostDebugEvent += (ss, ee) => {
    if (ee.CallbackType == ManagedCallbackType.OnBreakpoint)
    {
        // here do what you want and then you can
        // process.StepInto, StepOver, or StepOut to move from here
    }
};
