Answer 1

For the sake of completeness, I'll include the final code which is a stripped down version of the sample @Sock linked to in the 'Build your own XML Parser' section of the answer. @Sock's answer is still the most complete answer, but this sample should be useful for anyone looking for a quick, simple code sample for ASP.NET Core.

Model

public class FeedItem
{
    public string Link { get; set; } 
    public string Title { get; set; } 
    public string Content { get; set; } 
    public DateTime PublishDate { get; set; } 
}

Controller

public class ArticlesController : Controller
{
    public async Task Index()
    {
        var articles = new List();
        var feedUrl = "https://blogs.msdn.microsoft.com/martinkearn/feed/";
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri(feedUrl);
            var responseMessage = await client.GetAsync(feedUrl);
            var responseString = await responseMessage.Content.ReadAsStringAsync();

            //extract feed items
            XDocument doc = XDocument.Parse(responseString);
            var feedItems = from item in doc.Root.Descendants().First(i => i.Name.LocalName == "channel").Elements().Where(i => i.Name.LocalName == "item")
                            select new FeedItem
                            {
                                Content = item.Elements().First(i => i.Name.LocalName == "description").Value,
                                Link = item.Elements().First(i => i.Name.LocalName == "link").Value,
                                PublishDate = ParseDate(item.Elements().First(i => i.Name.LocalName == "pubDate").Value),
                                Title = item.Elements().First(i => i.Name.LocalName == "title").Value
                            };
            articles = feedItems.ToList();
        }

        return View(articles);
    }

    private DateTime ParseDate(string date)
    {
        DateTime result;
        if (DateTime.TryParse(date, out result))
            return result;
        else
            return DateTime.MinValue;
    }
}
