Я пытаюсь получить Native Messaging между моим расширением chrome и моим приложением на c #. JavaScript работает нормально, но я получаю эту ошибку:

Ошибка при связи с собственным хостом обмена сообщениями.

Приложение запускается вместе с расширением, как я видел из диспетчера задач. Вот мой код C #.

private static string OpenStandardStreamIn()
{
    //// We need to read first 4 bytes for length information
    Stream stdin = Console.OpenStandardInput();
    int length = 0;
    byte[] bytes = new byte[4];
    stdin.Read(bytes, 0, 4);
    length = System.BitConverter.ToInt32(bytes, 0);

    string input = "";
    for (int i = 0; i < length;i++ )    
    {
        input += (char)stdin.ReadByte();
    }

    return input;  
}

private static void OpenStandardStreamOut(string stringData)
{
    //// We need to send the 4 btyes of length information
    string msgdata = "{\"text\":\"" + stringData + "\"}";
    int DataLength = stringData.Length;
    Stream stdout = Console.OpenStandardOutput();
    stdout.WriteByte((byte)((DataLength >> 0) & 0xFF));
    stdout.WriteByte((byte)((DataLength >> 8) & 0xFF));
    stdout.WriteByte((byte)((DataLength >> 16) & 0xFF));
    stdout.WriteByte((byte)((DataLength >> 24) & 0xFF));
    //Available total length : 4,294,967,295 ( FF FF FF FF )
    Console.Write(msgdata);
}

И основная функция:

static void Main(string[] args)
{
    string message = "test message from native app.";
    OpenStandardStreamOut(message);

    while (OpenStandardStreamIn() != null || OpenStandardStreamIn() != "")
    {
        OpenStandardStreamOut("Received to Native App: " + OpenStandardStreamIn());
        OpenStandardStreamOut("Recieved: " + OpenStandardStreamIn());  
    }
}

Код JS:

var host_name = "com.example.native";
var port = null;

connectToNative();
function connectToNative() {
    console.log('Connecting to native host: ' + host_name);
    port = chrome.runtime.connectNative(host_name);
    port.onMessage.addListener(onNativeMessage);
    port.onDisconnect.addListener(onDisconnected);
    sendNativeMessage("test");
}

function sendNativeMessage(msg) {
    message = {"text" : msg};
    console.log('Sending message to native app: ' + JSON.stringify(message));
    port.postMessage(message);
    console.log('Sent message to native app: ' + msg);
}

function onNativeMessage(message) {
    console.log('recieved message from native app: ' + JSON.stringify(msg));
}

function onDisconnected() {
    console.log(chrome.runtime.lastError);
    console.log('disconnected from native app.');
    port = null;
}

Host Manifest:

  "name": "com.example.native",
  "description": "Native support for Chrome Extension",
  "path": "NativeApp.exe",
  "type": "stdio",
  "allowed_origins": [
