CSharp: Uri.IsWellFormedUriString return true wrongfully

Question

Why

Uri.IsWellFormedUriString("http://www.foo@foo.com", UriKind.Absolute);

return true ?!

Can we use @ in a website domain?!!!

Yes you can. The part before the @ sign is the username.

Yes we can.

If you put this url in your browser, it will warn you (at least my firefox does so) that you are trying to authenticate with foo.com as user www%2Efoo.

The @ is used to separate user credentials from the address. This is rarely used with http, but more often with ftp: ftp://user:password@domain.com.
