c# - .NET Core - Selenium RemoteWebDriver - PlatformNotSupportedException

Question

我正在尝试使用 .net core 2 和 xunit 运行 Selenium 测试

作为 Selenium 服务器，我使用 docker 容器，如下所述: https://github.com/SeleniumHQ/docker-selenium

使用命令运行容器:
docker run -d -p 4444:4444 -v/dev/shm:/dev/shm selenium/standalone-chrome

测试代码

public void Test()
{
    IWebDriver driver = new RemoteWebDriver(new Uri("http://127.0.0.1:4444"), new ChromeOptions());
    driver.Navigate().GoToUrl("https://www.google.com");
    var s = ((ITakesScreenshot)driver).GetScreenshot();
    s.SaveAsFile("screen.jpg");
}

当我尝试运行测试时出现异常:

System.PlatformNotSupportedException : Operation is not supported on this platform.
   at System.Net.SystemWebProxy.GetProxy(Uri destination)
   at System.Net.ServicePointManager.ProxyAddressIfNecessary(Uri& address, IWebProxy proxy)
   at System.Net.ServicePointManager.FindServicePoint(Uri address, IWebProxy proxy)
   at System.Net.HttpWebRequest.get_ServicePoint()
   at OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest(HttpRequestInfo requestInfo)
   at OpenQA.Selenium.Remote.HttpCommandExecutor.Execute(Command commandToExecute)
   at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
   at OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities)
   at OpenQA.Selenium.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities)
   at Automation.LoginTests.Test() in C:\Git\Automation\test\Tests\LoginTests.cs:line 29

当我在 linux (Debian 9) 或 Windows 10 上运行时，结果相同。难道我做错了什么？ Selenium 似乎可以支持.NET Core 2
