Hi, After the initial OAuth user interaction, you can still perform operations without further user interaction with the *Installed Application* and *Web Application* flows as long as you request offline access<https://developers.google.com/adwords/api/docs/guides/authentication#offline_access>. Due to its complexity I recommend considering these other flows before trying to use the service account flow.
Please take a look at the .NET OAuth wiki<https://github.com/googleads/googleads-adwords-dotnet-lib/wiki/How-to-create-OAuth2-client-id-and-secret> and post back if you still have trouble with the setup.
