Ready.
The nanoDevice runtime is loading the application assemblies and starting execution.

Description

I am not sure if nanoFramework.System.Device.Wifi itself the problem but if new blank project, the program is uploaded and executed. But if I add the library via nuget manager it does not work anymore. After the upload it does not print anything. So cannot even tell if debug maybe is broken there or controller at self does not execute.

My goal is to connect wifi, and start webserver to show later some values. Hard to achieve. Same thing I tested now with arduino editor. The examples like simple webserver works. So I am also not sure if memory is the problem or what else.

I am new to this btw.

How to reproduce

1. Visual Studio 2026 - New Project
2. Select blank nanoFramework
3. Add via nuget manager nanoFramework.System.Device.Wifi
4. Deploy and Debug

using System.Diagnostics;
using System.Threading;

namespace NFApp2
{
    public class Program
    {
        public static void Main()
        {
            Debug.WriteLine("Hello from nanoFramework!");

            Thread.Sleep(Timeout.Infinite);

            // Browse our samples repository: https://github.com/nanoframework/samples
            // Check our documentation online: https://docs.nanoframework.net/
            // Join our lively Discord community: https://discord.gg/gCyBu8T
        }
    }
}

Expected behaviour

After the line "The nanoDevice runtime is loading the application assemblies and starting execution." it should start to execute and print out the debug lines.

Without Wifi library I get this after the above line.

The hello world project is working. Are you saying that with the Wifi Nuget added you do not get the Hello from nanoFramework! printout?

Yes correct.

Sorry for late response. I was sick and totally forgot about this. At the moment I cannot test anymore because I used the native language to make process.
