ASP.Net MVC 4 Razor: Section Defined But Not Rendered Error:
                            In asp.net mvc 4 project development  you may face an error like "The following sections have been defined but have not been rendered for the layout page "~/Views/Shared/_Layout.cshtml": "Class". and / or "The following sections have been defined but have not been rendered for the layout page "~/Views/Shared/_Layout.cshtml": "scripts".

It means that you have no definition for  a section in your master Layout.cshtml, but you try to get that section from your View. To resolve this problem, check your view.cshtml has some thing like this

@section Class{
}

and / or

@section scripts{
}

If yes, you must define a section in your master Layout.cshtml like this
To fix this section defined but bot rendered error you just add this lines before the end of body tag in your Layout.cshtml

 @RenderSection("scripts", required: false)

 @RenderSection("Class", required: false)
