ArcGIS Runtime SDK for .NET comes with a RoutingTask which works great for solving routing problem. We need to tackle a different type of network problem, namely -- solving for Closest Facility. Is that even possible within Runtime SDK if we are provided with a routing package? I see that this is supported in other Runtime platforms, but not in .NET. If it is not possible in the SDK, is this type of network solving available in ArcGIS for Server? Any other suggestions?
