>How do you go to a line in debugger of ASP.NET? Similar to how F7 works in VFP?

In addition to the answers Rick and John have given you, I will add that all the major browsers have excellent debugging tools. Some are built in and some are add-ons. I have read that some developers have adopted Firefox simply to be able to use Firebug.
