headless browser for ASP.NET

I am developing full ajax web app. So I need to develop google crawlable app, also I must create snapshot for googlebot.

Do you know headless browser works with javascript and ajax for ASP.NET ?

I found XBrowser but right now it hasn't JavaScript support.

sorry for my English :).
