InvalidOperationException: This version of ChromeDriver only supports Chrome version X (SessionNotCreated)

[StanlyLife]

@rosolko Thank you for taking your time and investigating the issue. it seems like my chrome is of version 85.

**Google Chrome** | 85.0.4183.83 (official version) (64-bit) (cohort: 85_83_Win)
**Versjon** | 94abc2237ae0c9a4cb5f035431c8adfb94324633-refs/branch-heads/4183@{#1658}
**OS** | Windows 10 OS Version 1903 (Build 18362.1016)

However, in the console of the application, it seems to be running (driver) version 83.0.4103.39

Starting ChromeDriver 83.0.4103.39 (ccbf011cb2d2b19b506d844400483861342c20cd-refs/branch-heads/4103@{#416}) on port 56769

I thought WebDriverManager was supposed to update this automatically(?)

Hey @rosolko I am having the same problem as @StanlyLife , I have version 85.0.4183.83 in chrome browser, however, it seems that the manager is not being able to update automatically to the latest chromeDriver, which is 85.0.4183.8700, it is trying to use the version 83 instead.

I also thought the WebDriverManager would pick up the latest version of the driver automatically.

@StanlyLife Can you please check your Chrome browser and Chrome driver versions.

[StanlyLife]

@rosolko Any thoughts?

UPDATE

Turns out I had installed Selenium.webdrivers.chrome and it was referring to version 83 of the extension... I downgraded to 81 to test and the same error message occurred except it said 81, not 83. I then removed that extension due to browser incompatibility and manually downloaded the driver and set envpath variables, this works.

I then removed the path from ChromeDriver(@"C:\WebDrivers", chromeoptions); and it automatically targets the former extension's version and tries to initiate a webdriver of version 81.

So I looked through the documentation again and saw:

Notice that simply adding new DriverManager().SetUpDriver() does magic for you:
It checks the latest version of the WebDriver binary file
It downloads the binary WebDriver if it is not present in your system

Does this mean that It will not update the webdriver automatically if there already is an older version located on the computer? If that is the case how does the extension check or rather where the other webdrivers exists?

Adding new DriverManager().SetUpDriver(new ChromeConfig(), "Latest", Architecture.X64); Installed webdriver inside project folder. However, selenium does not seem to take the webdriver into consideration and is not using it without it beeing specified

I think that your initial implementation, in the very first comment above, it is perfectly fine. I am using the same one and it is working in Production.

Does this mean that It will not update the webdriver automatically if there already is an older version located on the computer? If that is the case how does the extension check or rather where the other webdrivers exists?

I am not sure but I think, Yes, this is what does this mean.
I was used to add the WebDriver in my project manually and use it the same way as you do. But since I am using the WebDriver Manager I Deleted the driver from my project and I am letting the Manager to deal with that. After all it is Downloading the Latest Version, even if you look closer into the source code it is doing exactly that.
So my guess is that if you Remove the driver from your project all together and let the Manager do it's magic it will solve you problem ;)

Well here comes the other problem. Sometimes the Chrome is updating by itself(there are some ways to stop that but I am not a fan). In this case you have to restart your program(winService or whatever) and the Manager will download the latest version.
Probably there are ways to automate even that but this is different subject. Also in this issue #85 they implemented useful feature if you don`t want to update your browser.
