I was wondering if, just to develop, I could run an existing installation (that is running now with IIS) entirely from VS or Web Developer Express, without IIS. As with the instructions described here.

When I do this (open the root of the site with the "Open Website" option) and run the site, I see it first running, for example at "http://localhost:65369/DotNetNuke", using the development server as expected, but then there is a redirection to "http://localhost/dnn" (the site in IIS). So I still need to have the site configured in IIS.

This also happen with a fresh install, if I first configured and installed it with IIS (doesn't happen if I run it from VS from the first moment, like in Michael's guide) and then want to run it just with VS.

Maybe there is a setting or something else telling the site to run using the IIS URL?

This isn't a big trouble, but I would like to be able to develop modules for this site and run it without IIS, using just the development server.

Thanks so much in advance

Thanks for the answer.

I think my problem also was caused because the root directory name of the site (DotNetNuke in my example) was different to the site name (dnn). I changed the directory name to match the name of the site and opened the directory from VS with the option "Open Website".
 

Now I have the same portal alias to run the site from VS or IIS: localhost/dnn
And, from VS, the site can run using (regardless the port) an url like: http://localhost:53029/dnn/
