I am struggling with breakPoint issue in VS 2012 for more than hours. I am from eclipse background, there I never heard about such issues.
Problem :<
Running Visual Studio 2013 or Visual Studio 2015 RC, I've found that to get a breakpoint to work in a .js file I need two things to be true:
I need to start Visual Studio by right-clicking the VS shortcut and select "Run as administrator". (If right-clicking on the Taskbar icon, select the application shortcut icon from the pop-up menu and right-click on that to get a context menu that includes "Run as administrator".)
I need to set Internet Explorer as the default browser that will be opened for the web debugging session. If I choose Chrome or Firefox, the breakpoint doesn't work for me.
