The desktop version of Internet Explorer now has quite a good selection of developer tools available on any site by just pressing F12
Unfortunately on Windows Phone it’s been quite difficult to debug websites and so developers typically had to resort to alert(‘hello’); style debugging. With Update 2 for Visual Studio 2013 there is a new Debug menu item “Debug Windows Phone Internet Explorer”
This gives you the option to select the device/emulator and specify a launch site to debug.
The debugging experience is pretty cool as it’s actually in Visual Studio and includes the ability to set breakpoints and inspect variables.
Do also get the DOM Explorer
This has got to make our jobs easier!
