Tag helper `asp-append-version` doesn't work for ManifestEmbeddedFileProviders

[Daniel-Khodabakhsh]

Describe the bug

When using the asp-append-version tag helper on files served from ManifestEmbeddedFileProviders added via IApplicationBuilder.UseStaticFiles() the rendered HTML does not contain the version/hash query string.`

To Reproduce

Steps to reproduce the behavior:

1. Create an ASP.NET-Core web application
2. Create a folder with some static assets.
3. Add the appropriate <EmbeddedResource /> and <GenerateEmbeddedFilesManifest /> entries to your .csproj to embed the files from step number 2.
4. Use IApplicationBuilder.UseStaticFiles(new StaticFileOptions() {...}) in your Startpup.cs's Configure() step.
5. Add the tag helper to your .cshtml page via @addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers.
6. Add a reference to the file in a .cshtml page, including the asp-append-version tag helper. (<img src="..." asp-append-version="true">)
7. Notice the image doesn't get the query string ?v=.... appended to it.

Screenshots

The image on the top KnightSolaire.png is located in wwwroot while 4x8.png is embedded into the assembly.

Attempts

I tried to supply the manifest embedded file provider to both IApplicationBuilder.UseStaticFiles() and IHostingEnvironment.WebRootFileProvider as suggested here but this did not work.

var staticAssetFileProvider = new ManifestEmbeddedFileProvider(Assembly.GetExecutingAssembly(), "Assets");
app.UseStaticFiles(new StaticFileOptions
{
    FileProvider = staticAssetFileProvider,
    RequestPath = assetPathString
});
environment.WebRootFileProvider = new CompositeFileProvider(environment.WebRootFileProvider, staticAssetFileProvider);
