Hi,
I installed Visual Studio 17 with ArcGIS Run time for .Net 100.4 version and installed Local Server 100.3 as mentioned in Guide .
Local Server tested with below sample:
Local Server Services—ArcGIS Runtime SDK for .NET Samples | ArcGIS for Developers opers.arcgis.com/net/latest/wpf/sample-code/localserverservices.htm
Local server is Starting and then failed when i am using Geo processing service. but when i am selecting the Map service and Feature service it stated well . as show in below.

Please provide solution for this issue.
