I have a WPF FeatureLayer backed by an ArcSDE feature class that I hope to use for editing. After the layer is done initializing its readOnly property is true, I think that this points to some problem with the ArcSDE setup but I can't figure out what it could be.
I've verified that the connection is working, inspecting the FeatureLayer shows that it has downloaded the remote table name. The post installation setup for ArcSDE had no trouble, same with creating some empty feature classes, adding them to an mxd file and using it to host a feature service. Is there any other setup I may have missed?
