Is it possible to provide a background worker sample? about nowin

If I understood your question correctly - you don't even need to use BackgroundWorker.
Once you've created and started a server (see NowinSample/Program.cs as @Bobris mentioned) it will run until either stopped or disposed (so keep a reference alive, stop+dispose when no longer needed).
Nowin uses external threads (simplified a bit, don't recall if there is an option to flow execution context) to handle requests. This however might require additional care when dealing with forms and controls - namely something like this:

if (control.InvokeRequired) 
{
    control.Invoke(()=>...action...);
}
else 
{
    ...action...
}

My objective is to host some simple binary image file for an IoT Node Application.

Just look at NowinSample/Program.cs it cannot be much easier than that.
