I am try to create first ASP.NET web project and I get
this message:

"Unable to create web project 'WebApplication 1'. The
filepath 'C:\inetpub\www root" does not correspond to the
URL 'http://localhost/WebApplication1 '. The two need to
map to the same server location. HTTP Error 404: Object
Not Found
