@deltakosh Can we have some description ? I don't know what you mean by "content from github"

[deltakosh]

I would like to provide a C# sample that display github content like this page:https://github.com/Microsoft/UWPCommunityToolkit/blob/dev/docs/index.md

And so we could integrate Markdown files/code from the docs in the sample app, I suppose.

One thing not to forget is that it should support both Light theme (like in GitHub) and Dark theme (like in VS Code).

[deltakosh]

For doc support I'm working on it. Every sample will display the doc directly in the sample app

See #805

Are you working on it? I'll take it else

[Odonno]

No, you can do it if you want to.

[deltakosh]

ok I'm on it:)
