_Layout.cshtml(这是基本布局)

@RenderSection("something",required: false)
@RenderBody()

_Main.cshtml

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}
@section something {
   Hey I'm actually on the _Main layout.
}

Index.cshtml

@{
    Layout = "~/Views/Shared/_Main.cshtml";
}

当我尝试在一个动作中渲染索引视图时，我得到这个错误，

The “RenderBody” method has not been called for layout page
“~/Views/Shared/_Main.cshtml”.

但是等等，_Main.cshtml有一个已经有一个RenderBody()的父版本。
所以我错了，我必须为每个孩子布局调用RenderBody()？
