Description

To initiate Options object we have to write:

var options = new ChromeOptions { UseWebSocketUrl = true };

options.AddArgument("remote-debugging-port=9222");

At the same time we still have an access to:

options.Arguments // ReadOnlyCollection

In general it looks like

Have you considered any alternatives or workarounds?

What if we remove all Add* methods and allow collections to be natively mutable? It will significantly simplify usage:

var options = new ChromeOptions
{
  UseWebSocketUrl = true.
  Arguments = { "remote-debugging-port=9222" }
};

And finally even to be focused on driver initialization without any intermediate local variables:

var driver = new ChromeDriver(new ChromeOptions
{
  UseWebSocketUrl = true.
  Arguments = { "remote-debugging-port=9222" }
});
