There are a number of technologies being used within the service. This document will try to keep the high level tools/SDKs so that people can easily ramp on the project.
Configuration in this project uses ConfigurationManager.AppSettings. In order to make it easier to configure outside of web.config, ConfigurationBuilders are supported. Currently, there are three builders enabled: KeyVault, Environment, and User Secrets. For more details, see the project where they are maintained.
