I need to write a console application to retrieve domain shared contacts (eventually update, add or delete them, too).

What I found so far is "[Google Domain Shared Contacts API](https://developers.google.com/admin-sdk/domain-shared-contacts/)" should do just that, but I am a bit clueless as where to start.

I don't know how to access this API in .NET and I haven't found any examples of such a code.
