推荐答案
主要问题是您正在渲染不带布局的局部视图.渲染部分视图时，它将仅渲染您指定的代码，但是您创建了一个节，该节除了Layout.cshtml之外均未渲染，但是布局未在任何地方调用.要解决此问题，您必须将布局代码添加到局部视图中.
The main issue is that you are rendering a partial view without a layout. When you render the partial view it will only render the code you specify, however you created a section that is not rendered anywhere except the Layout.cshtml however the layout is not invoked anywhere. To fix this you have to add the layout code to your partial view.
@model myApp.viewModel
@{
Layout = "~/Views/Shared/Layout.cshtml"; // <---- adding the layout
}
@section userProfile{
<div>@string.Format("{0}, {1}", Model.lastName, Model.firstName)</div>
@foreach (var item in Model.Locations)
{
<div>
<ul class="row">
<li class="cell">@item.LocType</li>
<li class="cell">@item.LocName</li>
<li class="cell">@item.UserRole</li>
</ul>
</div>
}
}
考虑到这一点，我认为您应该使用@ Html.Partial("); 不是渲染部分. 请查看此链接，例如 http://mvc4beginner.com/Tutorial/MVC- Partial-Views.html
After thinking about this i think you should be using @Html.Partial(""); not Render section. Take a look at this link for example http://mvc4beginner.com/Tutorial/MVC-Partial-Views.html
