I'm writing an Extension for ArcGIS Pro. This Extension is creating special Layers which has to be recognised after saving and loading an aprx-File.
In ArcObjects I used the ILayerExtensions and stored a unique String in the Layer to identify it after loading a MXD.
What equivalent do you recommend for ArcGIS Pro? Is there a new/better way to store Data in a Layer or APRX-File?
Thank you for your Help.
