MVC 4 and Robots.txt Usage?

I've been using a Robots.txt file for years using ASPX web sites. Just curious if its needed with MVC 4?  Also curious is Ignore Routes is useful for Robots?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Robots.txt is what it is, a file to help search engines know what to index.  IMHO it is needed for all public-facing web sites.

Ignored routes are useful to reduce the "noise" from some requests, or to avoid routing when you have special HTTP handlers in place.

On my internal web sites, I always ignore a long list of stuff, including Robots.txt requests.
