'System.ServiceModel.FaultException' error

Hi Experts,

I created a custom service in D365 and tried accessing the service from a C# console application.

Build is successful in the console application; however, when I run the application, system is throwing below error

An unhandled exception of type 'System.ServiceModel.FaultException' occurred in mscorlib.dll

Any pointer would help.

Thanks,

N.Sridhar
