Isolation Trace works in Pro but fails using .net SDK

[khem1000]

Hi,

I am using ArcGIS Runtime 200.3

I have set up a named trace to do an Valve Isolation Trace. I can run the trace successfully in Pro against a mobile geodatabase containing UN. The only input parameter I am providing is the starting point. 

I then tried running the same trace using .net sdk, which I have created using sample codes from Offline utility networks in ArcGIS Maps SDKs for Native Apps

I am using same the same starting location i.e. in same DMA, same named trace, same mobile geodatabase in both Pro and .net

But in .net, I am getting error:

"Tracing failed. Invalid subnetwork controllers found". 

I can see there is a valid subnetwork controller for this particular DMA. 

At other starting points (different DMAs), the trace works successfully in both .net & Pro.

Any idea why the trace could possibly fail using .net SDK, while it works in Pro

Are you able to try with 200.8 and see if that makes a difference? (even if you aren't able to permanently move to it, if there's a version it started working might help us narrow the issue down). A lot has changed in utility network support since 200.3
