I created a .net application within visual studio.net (old version) The web site that was created has the following path: http://localhost/WebSite1/Default.aspx I also created a web site using the ms visual web developer 2010 express. It created the following path: http://localhost:2452/WebSite1/Default.aspx Here they are next to each other: http://localhost/WebSite1/Default.aspx http://localhost:2452/WebSite1/Default.aspx Why does the 2010 version create it with a 2452 within the address. Separately, should both of these applications (website1) be visable within the IIS directy as along with the other web sites I have created? I can not locate them. Any detail woudl be appreciated.
