Custom Resources for DSC on Linux

Does anyone know where there’s some kind of documentation or helpful information on developing custom resources for DSC on Linux? I’ve been looking around and I don’t see anything “definitive” except for some MSDN articles on using Visual Studio for an MI provider which strikes me as more Windows centric than Linux centric?

There isn’t. What’s been done was all by the Unix services team. It’s all open source though, so there should be a ton of examples to peruse.
