I am converting a fully working C# Web Application from REST API to GRAPH API, using FB C# SDK 6.0. I have been able to obtain access token and post event to my "personal" Facebook page without problem. But I need to post the event to the Page associated with my Web Application (for which I am the Admin). I am totally at a loss as how to obtain the required access token, and construct the "fbClient.Post" call to create the event. I could find no relevant example with the SDK. And I have spent many hours researching this and other forums etc.
Any help or even clues would be much appreciated.
