Question XDocument.Load

On p812, in chapter 27, a code fragment is listed which tries to load an http stream directly into an XDocument. It generates this error message:
"Cannot open 'http://blog.cninnovation.com/feed/atom/'. The Uri parameter must be a file system relative or absolute path."

Am I missing something?

Hi Nico,
thanks for this information. This was a change with .NET Core that I missed.
Making HTTP Requests with XDocument.Load is now only available from the full .NET Framework. XDocument.Load only loads it locally. I've made a change to the sample code to use the HttpClient before using XDocument:

Code:
var httpClient = new HttpClient();
using (Stream stream = await httpClient.GetStreamAsync("http://csharp.christiannagel.com/feed/atom/"))
{
    XNamespace ns = "http://www.w3.org/2005/Atom";
    XDocument doc = XDocument.Load(stream);
    //...
The code is already available on https://github.com/ProfessionalCShar...ssionalCSharp6

Hope this helps,
