Visual Studio Additional process debugging

1. Build a WebApplication project and add Default.aspx page
2. Add an IIS Web site
3. Open the page, Task Manager started the process: w3wp.exe
4. Attach process, way: vs-Debug-Attach Process
5. The browser opens the page default.aspx, at which point the breakpoint is entered and you can debug

First step: Build a WebApplication project and add Default.aspx page

Step Two: Add an IIS Web site, physical address, point to the project path, for example: D:\Documents\visual Studio 2013\projects\webapplication3\webapplication3

Step three: Open the page, Task Manager started the process: w3wp.exe

Fourth step: Attach process, Mode: vs-Debug-Attach Process

Note that the process w3wp.exe cannot be found at this time. Turn off vs, start vs with Administrator, open the previous WebApplication project, click vs-Debug-Attach process, you can find the process

The fifth step: The browser opens the page default.aspx, this time enters the breakpoint, may debug
