Thanks weskroesbergen for opening a Pull Request! The reviewers will test the PR and highlight if there is any conflict or changes required. If the PR is approved we will proceed to merge the pull request 🙌

@weskroesbergen shouldn't you also update the parsers ? It all seems to be a manual XML parsing.
You should add a description to your PR using the default template.

@weskroesbergen did you have some time to look into this? Thanks in advance!

Build failing due to whitespace:

  "D:\a\1\s\Windows Community Toolkit.sln" (Build target) (1) ->
       "D:\a\1\s\UnitTests\UnitTests.UWP\UnitTests.UWP.csproj" (default target) (2) ->
       "D:\a\1\s\Microsoft.Toolkit.Parsers\Microsoft.Toolkit.Parsers.csproj" (default target) (5:3) ->
       (CoreCompile target) -> 
         Rss\RssSchema.cs(64,1): error SA1028: Code should not contain trailing whitespace [D:\a\1\s\Microsoft.Toolkit.Parsers\Microsoft.Toolkit.Parsers.csproj]

I think if we go through with #3200 then all that's left in Microsoft.Toolkit.Parsers is the RSS one. I'm curious if our API can just be deprecated in favor of the .NET one here. @Sergio0694 do you know anything about this space or API?

@weskroesbergen could you provide more details on how you're using the RssParser in the toolkit and for what? Have you tried to use the .NET APIs above? Is there something wrong with them or is this API surface simpler? Any info you could provide would be really helpful.

Thanks!

Yup, investigated that the System.ServiceModel.Syndication API is just as easy to use as our RssParser. We should remove our RssParser and tell folks to use that one instead.

            XmlReader reader = XmlReader.Create(RssFeedLocation);
            SyndicationFeed feed = SyndicationFeed.Load(reader);

            reader.Close();

            foreach (SyndicationItem element in feed.Items)
            {
                Console.WriteLine($"Title: {element.Title.Text}");
                Console.WriteLine($"Summary: {element.Summary.Text}");
            }

I'm going to close this issue. @azchohfi can you remove the RSS Parser as part of #3435? I created Doc Issue to track migration guide.

Done.

@michael-hawker was using RSS parser to generate a feed, but don't depend on it anymore.
