    Normally, you create a view or page that generates XML for the site map from a data source.  The data source can be files on disk, content in a database etc. It depends on your project. You wouldn't actually start with an XML file. You could do that same thing with robots.txt - mapping the URL to a Razor Page, for example, that is designed to output text/plain. Here's an example Razor Page that could work as your sitemap:

    @model SitemapModel
        Layout = null;
    <?xml version="1.0" encoding="utf-8" standalone="yes" ?>
    <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
        @foreach (var item in Model.Items)

    Model.Items is a collection of data that you want to display. The ToW3CDate method is an extension method that outputs a DateTime to a format that is valid for the Sitemap protocol:

    public static class DateTimeExtensions
        public static string ToW3CDate(this DateTime dt)
            return $"{dt.ToUniversalTime().ToString("s")}Z";
