Link Checker / Validator, preferably for automatic builds?

I am doing some preliminary research into a'link checker' for a (.net) website. The basic idea is that this tool would crawl through the website and check to see if the links in it are functional and lead to a valid page. I've seen some of the posts here, but I am loo开发者_JAVA百科king for more of a standard tool.

Also If there is any way that this could be part of an automatic build process, that would be great.

Is there a MS / standard tool for this? This seems like it would be common enough ... how do you guys do it?

You could automate link checker (supports command line) with A1 Website Analyzer. But it does not yet have an options for an emergency popup if errors are found :) But it could be added.
