Attach to Any ASP.NET Web Server from Visual Studio in One Click

This is an update to my previous blog post Attach to Visual Studio Development Server with One Click.

The Visual Studio Macro from previous article doesn’t support IISExpress or IIS; it only supported the Visual Studio Development Server, more over it doesn’t detect latest Development Web Server WebDev.WebServer40.exe.

Now I have updated the Macro so that it will automatically detect the Web Server setting from the project properties and attach it accordingly.

Below is the code for the new Macro, I think it is self-explanatory
