How to set Chrome preferences using Selenium Webdriver .NET binding?

by

If you have updated to Chrome Version 36.0.x and Selenium 2.42, Martins solution no longer works.

It seems to have been updated. You now can use the following code 

ChromeOptions options = new ChromeOptions();
options.AddUserProfilePreference(string preferenceName, object preferenceValue);

I currently use it to change my Printer settings to “Save as PDF” instead of the default using this code as an example 

ChromeOptions options = new ChromeOptions();
options.AddUserProfilePreference("printing.print_preview_sticky_settings.appState", "{\"version\":2,\"isGcpPromoDismissed\":false,\"selectedDestinationId\":\"Save as PDF\");

I thought Martin’s solution was very good and accurate, but it suddenly stopped working for me, so naturally I had to see if I could find a solution.
