Start debugging faster by "Attach to Process"

Most ASP.NET developers use the standard F5 (Debug/Start Debugging) to start debugging from Visual Studio. However, there is a much faster way to start debugging if you already have an instance of your web application running. Just attach to it instead:

• Choose Debug/Attach to Process.
• Select the “aspnet_wp.exe” process and choose Attach.

Debugging this way is faster because you skip the often-lengthy compilation step, and you don’t have to navigate from the start page to the actual page that you want to debug.
