Does RenderSection() work inside ASP.NET Core's <environment> tag-helper?
Layout has this:
<!DOCTYPE html>
<html>
<head>
<environment names="Development">@RenderSection("devCss", required: false)</environment>
<environment names="Staging,Production">@RenderSection("staproCss", required: false)</environment>
</head>
<body>
@RenderBody()
<environment names="Development">@RenderSection("devJs", required: false)</environment>
<environment names="Staging,Production">@RenderSection("staproJs", required: false)</environment>
</body>
</html>
View has this:
@section devCss { <link rel="stylesheet" href="foo.css" asp-append-version="true" /> }
@section staproCss { <link rel="stylesheet" href="foo.min.css" asp-append-version="true" /> }
@section devJs {}
@section staproJs {}
<h1>hello</h1>
When RenderSection() is outside the <environment> tag, everything works.
When inside, as in above example, it fails with the unhelpful error of InvalidOperationException: The following sections have been defined but have not been rendered by the page at '_Layout.cshtml': 'staproCss, staproJs'. To ignore an unrendered section call IgnoreSection("sectionName").
That obviously makes no sense, as all sections were defined. And it complained about some, and not the others.
Does the <environment> tag-helper allow RenderSection() within it?
Answer
Just Add @RenderSection("Scripts", required: false) in end of </body> tag.
