I need to be able to build an app that pulls phone numbers from my CRM along with the "handling rep," then creates a custom answering rule with that info so that anyone calling with a number matching that list, gets routed to their rep. I'm a VB programmer so I am trying to use C# and convert it but I can't initialize the RestClient. If I pull the example in C# and put it in a C# project I also get errors. I'm trying to use the RingCentral.Net version 5.11.0 from GitHub.
