I am a C# Winforms programmer. Recently I started learning MVC with Dev Extreme and started working through [the tutorial here][1] I found the tutorial project would build in Visual Studio 2013, but that the application would not work correctly ( a button would not appear). This puzzled me for some time until I realized that the incorrect references inside the .cshtml file were not causing the build to break as they would in a Winforms project. What software or development environment is there to assist with debugging HTML code? [1]: http://js.devexpress.com/Documentation/Tutorial/UI_Widgets/Add_Widget_to_MVC_Project/?version=15_1
