General

A nuget package that provides a class SortedHtmlDirectoryFormatter derived from HtmlDirectoryFormatter ^Link, which will render the file list sorted by the LastModified property in descending order.

Usage

dotnet add package SortedHtmlDirectoryFormatter

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseDirectoryBrowser(new DirectoryBrowserOptions
    {
        FileProvider = new PhysicalFileProvider(rootDirectory),
        RequestPath = "/your-request-path",
        Formatter = new SortedHtmlDirectoryFormatter()
    });
}

Background

The extension method UseDirectoryBrowser generates a table that sorts the output by filename. This is not a super helpful behavior when it comes to some scenarios. e.g. Directory Browser on a folder full of files with random file names.

According to this github issue there is no plan to add a feature to sort this.

Hence I created this nuget package for this.
