Versioned content URLs in ASP.NET MVC 5

AspNet.Mvc.AssetVersioning

Adds a UrlHelper.VersionedContent URL extension helper to append SHA256 hash to content URLs in ASP.NET MVC 5.

Install

Install-Package AspNet.Mvc.AssetVersioning

Usage

In Views/web.config, add:

<configuration>
  ...
  <system.web.webPages.razor>
    <pages ...>
      <namespaces>
        ...
        <add namespace="System.Web.Mvc.AssetVersioning"/>
      </namespaces>
    </pages>
  </system.web.webPages.razor>
</configuration>

You can then use the helper in .cshtml files like so:

<script type="text/javascript" src="@Url.VersionedContent("~/scripts/jquery.js")"></script>

And the helper will append a query string parameter containing the SHA256 hash of the content. This is cached for the lifetime of the request cache (HttpContext.Cache).

aspnetmvc5-asset-versioning's Issues

Possible issue with slashes

I am seeing generated version hashes like this:

/scripts/lib/jquery.js?/7Vw4usZo39WYsHCrdNjIFHX6JYo92Sg0aGXnWU6GrM=

And seeing reports in instrumentation logs of browser console errors with this script seemingly undefined -- correlation not causation but seems worth it to spit out hex-only hashes or something more friendly.
