I've created an ASP.NET MVC 3 application and generated sitemap.xml using some free online tools.
It contains the following URLs:
http://www.mydomain/ http://www.mydomain/About http://www.mydomain/Portfolio http://www.mydomain/Contact http://www.mydomain/Sitemap
But when I uploaded sitemap.xml to Google Webmaster tools, I got these numbers:
URLs submitted: 5 URLs in web index: 1
