Create FeatureLayer with offline data

[Kristian]

I'd like to use the Clustering Feature Reduction for a bunch of MapPoints. The data is not in a portal or geodatabase and I'm struggling to see how I can create a FeatureLayer with this data (since a FeatureLayer is a requirement for using the FeatureReduction tool). There is an example for javascript which gives this capability here. I do not see how to achieve this in .NET as the FeatureTable is abstract. So, anyone able to suggest a way of creating a FeatureLayer from data in an arbitrary model, rather than data from a portal or geodatabase? Thanks.

In the Native Maps SDKs you have a couple of options, depending on whether / how you want to persist the layer. 

• FeatureCollectionLayer: Temporary in the Map unless the feature layer is saved as a portal item or the map itself is saved to a portal.
  • Sample: Feature collection layer | ArcGIS Maps SDK for .NET | ArcGIS Developers
• Mobile Geodatabase: Persisted as a .geodatabase file on disk.

Thanks Michael - the FeatureCollectionLayer sample is what I'm after 🙂
