Does the .NET SDK have an equivalent to the javascript GeoJsonLayer?

I've been using the GeoJsonLayer with the ArcGIS javascript API to load a GeoJSON file from a url and display the resulting shapes on a map. Is there an equivalent layer in the .NET SDK (e.g. similar to the KmlLayer)? If not, what is the typical workflow for getting GeoJSON data on a map using the .NET SDK?

Thanks,

There's no out-of-the-box support for GeoJson in the runtime.

To do this you'd need a GeoJson parser and create a FeatureCollectionTable or GraphicsOverlay and populate it based on the contents of the json you parsed.

There's quite a few 3rd party geojson parsers you can use: NuGet Gallery | Packages matching geojson

Thanks Morten, I'll explore that option. I suppose just pre-converting the GeoJSON to KML (or converting on the fly) and using KmlLayer is an option too.
