C# .net Zoho CRM V2 API sample?

C# .net Zoho CRM V2 API sample?

Does anyone have advice or a sample of how to connect to V2 API from a C# .net application?  My scenario is that I'm developing a Windows Desktop application that needs to lookup contacts by phone number in Zoho.  Looking at the authentication APIs I'm confused in that it sounds like somehow I'm supposed to setup a web server but I can't see how I'd do that with a normal desktop application.

Also, it appears that the third party .NET interfaces for Zoho are based on the V1 interface which is end of life.  Is anyone aware of third party Zoho interface for .NET which support the V2 interface?

Thanks!
