HtmlWeb User Agent

I am using HtmlAgilityPack to grab a table from a web page.

HtmlWeb web = new HtmlWeb();
HtmlDocument doc = web.Load("http://test.com");

I am aware that HtmlWeb has a UserAgent property, however I have no idea how I am supposed to attach a user agent to the header of the httprequest.

HtmlWeb web = new HtmlWeb().UserAgent("asdf");

returns the error

Error   1   Non-invocable member 'HtmlAgilityPack.HtmlWeb.UserAgent' cannot be used like a method.
