I originally created the project with authentication, but then decided to disable it. I had to remove this in the WebApiConfig.cs file. Make sure you have this if you intend to enable authentication.

        // Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
