And what is Desktop, Chopped Liver ?
James has pointed out how ESRI is focusing more on Server than Desktop at the upcoming Dev Summit. This is not just in terms of Conference resources. There are cool & useful things in ArcGIS server that have no equivalent in Desktop.
For example, take a look a the FeatureGraphicsLayer, available in AGS. This handy class inherits from DataTable.
So what about desktop? I can create an in-memory featureclass via an InMemoryWorkspaceFactory (by trial and error, there’s not much documentation). However, it’s still an IFeatureClass … it would really be better if I had a something like a layer that inherits from ADO DataTable that could be shown with a TableView in ArcMap.
