This is a partial implementation in C# for the Everbridge REST API, https://api.everbridge.net/
Unfortunately, the company does not supply a C# dll for their API. And the Swagger implementation that they have is incomplete and swagger-codegen is unable to produce a C# client dll.
So ... here's the partial implementation of the API that I needed.
This client uses Ucsb.Sa.Enterprise.ClientExtensions to manage the HttpClient's.
