问题
I am trying to move into the upgraded firefox web browser automation using selenium. It seems that selenium needs marionette driver to continue working. I followed the instructions set by the devs,
- downloaded the driver
- renamed it to wires.exe
The following code didnt manage to properly set the PATH to a custom path.
System.Environment.SetEnvironmentVariable("webdriver.gecko.driver", "@C:\DOWNLOADS\wires.exe")
so i added wires.exe to the debug\bin folder and then wires.exe worked properly but i got the following error
System.InvalidOperationException was caught Message=entity not found Source=WebDriver
this is the code i use to start webdriver
FirefoxOptions option1 = new FirefoxOptions();
option1.IsMarionette = true;
option1.AddAdditionalCapability("marionette", true);
driver = new FirefoxDriver(option1);

I too got the "Entity Not Found" error using FirefoxDriver(new FirefoxOptions()). It appears to be looking for firefox.exe in C:\Program Files (x86)\Nightly and not finding it. I found this working :
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService();
service.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
IWebDriver driver = new FirefoxDriver(service);

I try with this and it's working:
- Install FirefoxDevEdition
- Download geckodriver.exe
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(@"C:\Users\jmalpartida\Downloads\geckodriver-v0.8.0-win32", "geckodriver.exe");
service.Port = 64444;
service.FirefoxBinaryPath = @"C:\Program Files (x86)\Firefox Developer Edition\firefox.exe";
IWebDriver driver = new FirefoxDriver(service);

First of all, you need to add the driver to your system path, not as an env variable. Second, you need to set the flag in a desired capability, not a Firefox option. See: Marionette Webdriver
As such for remote webdriver:
DesiredCapabilities capabilities = DesiredCapabilities.Firefox();
capabilities.SetCapability("marionette", true);
var driver = new RemoteWebDriver(capabilities);
To add the webdriver to your windows path:
The easiest way is to open the start menu > search for environment > open edit the system environment variables > click on environment variables > search in the list for Path > click on edit > add ;C:\path\to\webdriver\location\wires.exe to the end and click save.
For your local (non-webdriver) tests you are right, you can run your webdriver using the following:
var driver = new FirefoxDriver(new FirefoxOptions());
You should not have to use
option1.IsMarionette = true;
option1.AddAdditionalCapability("marionette", true);
If you have set the driver path correctly in your path environment variable.
