将Visual Studio调试器附加到Electronic App

问题内容：

我正在尝试从头开始从Visual Studio 2017调试电子应用程序（而不是vscode）。

我创建了一个控制台nodejs项目，安装并保存了电子文件。项目

内容app.js（取自电子网站）：

'use strict';

const { app, BrowserWindow } = require('electron')
const path = require('path')
const url = require('url')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

function createWindow() {
    // Create the browser window.
    win = new BrowserWindow({ width: 800, height: 600 })

    // and load the index.html of the app.
    win.loadURL(url.format({
        pathname: path.join(__dirname, 'index.html'),
        protocol: 'file:',
        slashes: true
    }))

    // Open the DevTools.
    win.webContents.openDevTools()

    // Emitted when the window is closed.
    win.on('closed', () => {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        win = null
    })
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', () => {
    // On macOS it is common for applications and their menu bar
    // to stay active until the user quits explicitly with Cmd + Q
    if (process.platform !== 'darwin') {
        app.quit()
    }
})

app.on('activate', () => {
    // On macOS it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
    if (win === null) {
        createWindow()
    }
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

And index.html

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Hello World!</title>
</head>
<body>
    <h1>Hello World!</h1>
    We are using node
    <script>document.write(process.versions.node)</script>,
    Chrome
    <script>document.write(process.versions.chrome)</script>,
    and Electron
    <script>document.write(process.versions.electron)</script>.
</body>
</html>

但是，当我单击“开始”时，电子应用程序将启动，但调试过程似乎会自行脱离。当我尝试将调试器手动附加到所有电子过程（调试->附加到过程->选择所有电子过程）时，断点声称未命中，因为未加载任何符号。

我错过了一步吗？由于调试可以在VSCode上完成，因此我认为
它也可以在VS2017上完成？

非常感谢。

注意：我确实选中了“抑制JIT优化”，然后取消选中“仅启用我的代码”。

问题答案：

这实际上很容易做到。

在Visual Studio中配置您的应用程序：

启动您的应用。Electron将在单独的终端上启动，但不会将Visual Studio连接到它。

转到调试>附加到进程…，然后输入Webkit websocket连接类型和以http://127.0.0.1:5858为目标。

您的断点现已启用。
