Compile error: Line Suppression State Error CS0246 The type or namespace name 'Log' could not be found

[kiinoo]

Hello,

I tried to use the lib via nuget, but failed to find webclient assembly (search result it empty :-(

so i tried to build from source via visual studio 2022, but got the following compile error:

Severity	Code	Description	Project	File	Line	Suppression State Error	CS0246	
The type or namespace name 'Log' could not be found (are you missing a using directive or an assembly reference?)	Gripper.ChromeDevTools	c:\a\src\Gripper.ChromeDevTools\ChromeSession_Domains.cs	29	Active

any solutions?

thanks very much!

Hi, thanks for raising the issue.

I see that the Log namespace directory is missing from the repo. I'll try to fix that today.

However, builds for both Gripper.WebClient and Gripper.WebClient.Cdtr are on Nuget.

https://www.nuget.org/packages/Gripper.WebClient/0.6.1-alpha
https://www.nuget.org/packages/Gripper.WebClient.Cdtr/0.0.10-alpha

Note that they are still alpha. Did you make sure to tick the 'include prerelease' box in the VS Nuget package manager when you were searching for them?

thanks for quick answers,

I found the webclient then :)

but no luck to make the example code run:

	using Gripper.WebClient;
	using Gripper.WebClient.Extensions;
	using Microsoft.Extensions.DependencyInjection;

	try
	{
			var serviceProvider = new ServiceCollection()
			.AddGripper() // Register all services + default settings.
			.AddLogging()
			.BuildServiceProvider();

			var webClient = serviceProvider.GetRequiredService<IWebClient>(); // Fresh window driver.

			var cts = new CancellationTokenSource(TimeSpan.FromSeconds(30));

			await webClient.NavigateAsync(
					"https://tomaskrupka.github.io/Gripper/about",
					PollSettings.FrameDetectionDefault,
					cts.Token);

			var linksCountResponse = await webClient.MainContext.ExecuteScriptAsync(
					"document.querySelectorAll('a').length",
					cts.Token);

			Console.WriteLine($"Found {linksCountResponse.Result.Value} hyperlinks.");
	}
	catch (AggregateException ex)
	{
			foreach (var exception in ex.InnerExceptions)
			{
					Console.WriteLine(exception.ToString());
			}
	}

it stucked at var webClient = serviceProvider.GetRequiredService<IWebClient>(); // Fresh window driver.

with an exception:
