How to Debug Nop Commerce 2.8

I have the project built and deployed.  I want to debug the project inside VS2012.  When I try to build the Nop.Web part, it loads into the debug server and runs, but it sets up like it wants to install.  I need to debug this inside VS2012 so I can see variables and how they all work.  Thanks in advance.

How can I debug the Nop Commerce 2.8 project using the debugger in VS2012?

I don't think you can debug once you have gone live. You would usually set debug mode in the web.config.

So I can't run the debugger inside VS2012 and then use the dev server it builds so I can set break points in code and view variable values and things like that?
