Answer 1

According to this issue, System.ServiceModel.Syndication has not yet been ported to ASP.NET Core. Currently, this leaves you with 2 options:

• Target the full .NET framework to provide access to SyndicationFeed
• Build your own XML parser using .NET Core to reproduce the functionality you require

Target the full .NET framework

This is undoubtedly the easiest approach depending on your requirements.

If you will be deploying to windows only then you can run ASP.NET Core on top of the .NET 4.X framework. To do this, update your project.json from something like this

frameworks": {
  "netcoreapp1.0": {
    "imports": [
      "dotnet5.6",
      "dnxcore50",
      "portable-net45+win8"
    ]
  }
}

to this:

frameworks": {
  "net452": {
     "frameworkAssemblies": {
         "System.ServiceModel": ""
     }
   }
}

Build your own XML Parser

This will give you the most flexibility, in that you will still be able to run cross platform using the .NET Core framework. It requires a little more work to deserialise the string you have already obtained, but there are lots of examples on how to do just this, e.g. http://www.anotherchris.net/csharp/simplified-csharp-atom-and-rss-feed-parser/
