Dotnetcore 3.0 remote debugging from visual studio 2019 CE on Raspberry Pi 4 - insufficient rights

If there was anyone who could tell me how to remote debug a dotnetcore 3.0 console app from visual studio 2019 CE on a raspberry pi 4, I'd be happier.

plink -ssh -pw raspberry [email protected] "curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -r linux-arm -v latest -l ~/vsdbg"

is installed and runs on the PI

using Iot.Device.CpuTemperature;
using System;
using System.Device.Gpio;
using System.Threading;
namespace Raspi
{
    class Program
    {
        static void Main(string[] args)
        {
            CpuTemperature temp = new CpuTemperature();
            GpioController ctrl = new GpioController();
            int pin = 4;
            int wait = 5000;
            ctrl.OpenPin(pin, PinMode.Output);
            Console.WriteLine("Hello World!");
            int counter = 0;
            while (true)
            {
                Console.WriteLine($"The CPU temperature is {temp.Temperature.Celsius}");
                Console.WriteLine("counter=" + counter++);
                ctrl.Write(pin, PinValue.High);
                Thread.Sleep(wait);
                ctrl.Write(pin, PinValue.Low);
                Thread.Sleep(wait);
            }
        }
    }
}

Compiles without errors. Here some screenshots of the error behaviour:

vsbdg runs under root account
vsdbg can be found while browsing via ssh
And this error comes up
(translated from German) Error while connecting to the process: The .net debugger (vsdbg) doesn't have sufficient rights to debug the process. In order to debug the process, 'vsdbg' must be executed using root rights.

You can debug over SSH in Visual Studio.

So what you want to do is effectively this:

  • Make your hello world app
  • Set breakpoints in it where you want them
  • Build the app in debug, self contained
  • Deploy the app to your Rapberry Pi (it has to have SSH enabled on the Pi, running something like Raspbian)
  • Attach your debugger from VS 2019 to the Pi over SSH.

I wrote a longer article explaining exactly what I did here. It's the friend link so you don't get hit with Medium's paywall. It also means we're friends now.
