Do you have plans to put this library on NuGet? Thanks.

Do you have an example of how to subscribe to the page load event? The example below never fires.

session.Page.SubscribeToLoadEventFiredEvent((e) =>
{
	Console.WriteLine("Finished loading...");
});

I'm trying to navigate and capture a screenshot of a page. It works if I call Sleep(1000) and then capture, which leads me to believe that the issue is that I'm trying to capture the screenshot before the page fully loads.

Here's the full (non-working) example:

using (var session = new ChromeSession("ws://localhost:9222/devtools/page/" + targetId))
{
	var navigateResult = session.Page.Navigate(new Page.NavigateCommand
	{
		Url = "https://www.google.com"
	}).GetAwaiter().GetResult();

        // This does not work...
	session.Page.SubscribeToLoadEventFiredEvent((e) =>
	{
		Console.WriteLine("Finished loading...");
	});

	//System.Threading.Thread.Sleep(1000);

	Console.WriteLine("Taking a screenshot!");

	var screenshotResponse = session.Page.CaptureScreenshot(new Page.CaptureScreenshotCommand
	{

	}).GetAwaiter().GetResult();

	File.WriteAllBytes("ss\\" + Guid.NewGuid().ToString("N") + ".png", Convert.FromBase64String(screenshotResponse.Data));

	Console.WriteLine("Done.");
	Console.ReadKey();
}

Thanks

Let's look at GetBrowserProtocolForChromeVersion:
https://github.com/BaristaLabs/chrome-dev-tools-generator/blob/master/src/BaristaLabs.ChromeDevTools.Core/Chrome.cs#L148
It uses following URL:
$"https://chromium.googlesource.com/chromium/src/+/{chromeVersion.WebKitVersionHash}/third_party/blink/renderer/core/inspector/browser_protocol.pdl?format=TEXT"
I have Chrome 66.0.3359.139.
{chromeVersion.WebKitVersionHash} is a020eddf0d85fe84d4a6787b304f50aafb670969 in this case.
It is really exist such tree:
https://chromium.googlesource.com/chromium/src/+/a020eddf0d85fe84d4a6787b304f50aafb670969/
Also it has "/thirdparty", "/thirdparty/blink"... but hasn't "/thirdparty/blink/renderer" and next folders.

Conclusion: not each googlesource tree has all required files. Some another way should be used.

Possible work-around:
Open root tree URL. Remember parent tree URL. If current tree hasn't such file - open parent tree URL. And so until file found. But I am hasn't tried it and it is obviously it could take many time.

P.S. I could contribute if you will merge :)

Hi,
chrome-dev-tools-runtime library works great for us (debugging js), the only thing is that we are bound to .NET 4.5, so .NET Core is not an option for us at the moment. What is the best way to get this working on .NET Framework? Should the generator or the generated class library be changed? How difficult would it be in general?
Thank you.

I'm trying to run the generator and get the exception below.

Hello:
I don't quite understand your README.md file.
You mentioned "protocol definition file", I think, maybe you mean this file:
https://github.com/ChromeDevTools/devtools-protocol/blob/master/json/browser_protocol.json
From this file, I can see the latest browser_protocol is version 1.3.
But the code from this url is not working any more:
cyrus-and/chrome-remote-interface#10 (comment)
If I understand correctly, you need browser_protocol.json and js_protocol.json two Json files.
Then you can simply use the following code to download them. I hope the URLs can stay that way longer. #18 `class Program
{
private const string browser_protocol =
@"https://raw.githubusercontent.com/ChromeDevTools/devtools-protocol/master/json/browser_protocol.json";
private const string js_protocol =
@"https://raw.githubusercontent.com/ChromeDevTools/devtools-protocol/master/json/js_protocol.json";
private const string protocol_folder =
@"C:\Temp\ProtocolFiles";

static void Main()
{
WebClient webClient = new WebClient();
webClient.DownloadFile(browser_protocol, protocol_folder + "browser_protocol.json");
webClient.DownloadFile(js_protocol, protocol_folder + "js_protocol.json");
}
}
`
Please advice if I am correct in understanding your code.
Thanks,

i want to use "Input.dispatchTouchEvent" function,but i do not know how to set "type" parameter.

the Chrome DevTools Protocol Viewer describe like this.

Input.dispatchMouseEvent #
Dispatches a mouse event to the page.
PARAMETERS
type
string
Type of the mouse event.

thanks a lot.

There is problems with multithreading.
When we request Network.GetResponseBody for many requests at the same time in different threads, it gives body from other request for some of them. If we request one by one its ok.
