Working on my standalone box, I wanted to do some debuggign specifically in IIS 7.0.  It was quite easy to set up when you know how.  After a bit of digging here’s what I did.

• Created a VS2010 ASP.NET Web Application
• In WebSite Properties, select ‘Use Custom Server’ and enter in your base Url.
• In IIS 7.0 map your website root to a virtual directory and then convert the virtual directory into an Application.
• By default the DefaultAppPool runs under a hidden account IIS APPPOOL\DefaultAppPool which you need to give full control permissions  or at least Modify Permissions to the folder where your Visual Studio Web Application Projecty is.
• Hit f5 and you’re off.
• Note if you recycle the AppPool in IIS 7.0 it stops the w3wp.exe process and starts another, so your debugging will stop working.
• If you have any code in Application_Start in the Global.asax file it will not be run when you hit f5.  You Session_Start code will be however.

Cheers
