Rewrite rule for removing file extension

Hello all,

I've using Webmatrix/IIS Express to develop a ASP.Net application.While I was able to write most of the basic rules myself, I'm having difficulty with the below two items:


The file extension should be removed, replaced with a slash. Example below:
http://localhost/Home.aspx -> http://localhost/home/ Ensure that existing folder in the root directory work. For e.g. I have an admin folder in my site root so http://localhost/admin should point to it. I have only few folders so wouldn't mind if I had to create a rule for each of them.
Can anyone please specify the exact rules for the above that will go in the web.config's rewrite section.

Thanks,
...
