Is there a headless browser for .NET?
I am looking for this in a testing context.
Coming from Java I am thinking of something similar to HtmlUnit (http://htm
By browser remoting I assume you mean remotely controlling a 3rd party browser. Selenium offers a driver for the java browser, htmlUnit, which is a headless browser (no GUI). http://seleniumhq.org/docs/03_webdriver.html#htmlunit-driver
If you're adamant about sticking with pure .Net solutions, then you have a few useful options, although none of them are really great.
You can also consider looking at LiquidTest, but it's not cheap: developer licenses start at $2,000. And if you want to run it on a continuous integration server, that'll cost you another $1,000 for a server license.
IMO, while the libraries and languages in .NET provide some powerful features, the supporting toolset often falls short of competitors in other languages in some areas. Unfortunately, web integration testing is one of those areas.
You might want to check out the new Web Testing features of Visual Studio 2010:

You can download Beta 2 of VS2010 for free and try them for yourself.
