Используйте свой собственный движок просмотра
, используя
@Html.Partial("_CommonHtmlHead")
как
/Views/Shared/_CommonHtmlHead.html
или
/Views/MyArea/Shared/_CommonHtmlHead.htm
- это лучшее для меня.
Создание собственного механизма просмотра для этого с использованием восходящего класса System.Web.Mvc.VirtualPathProviderViewEngine представляется относительно простым:
/// <summary>
/// Simple render engine to load static HTML files, supposing that view files has the html/htm extension, supporting replacing tilda paths (~/MyRelativePath) in the content
/// </summary>

protected readonly CacheItemPriority? Priority;
private readonly bool _useCache;
public HtmlStaticViewEngine(TimeSpan? slidingTimeout = null, DateTime? absoluteTimeout = null, CacheItemPriority? priority = null)
{
_useCache = absoluteTimeout.HasValue || slidingTimeout.HasValue || priority.HasValue;
SlidingTimeout = slidingTimeout;
