   11. {
   12. class Program
   13. {
   14. static void Main(string[] args)
   15. {
   16. try

   31. var clientSecret = "2G_tDd4AM92Jv4j_a2hSa0mu05V5ddDr..";
   32. IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
   33. .Create(clientId)
   34. .WithTenantId(tenantId)
   35. .WithClientSecret(clientSecret)
   36. .Build();
   38. ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication);
   39. GraphServiceClient graphClient = new GraphServiceClient(authProvider);
   41. var groups = await graphClient.Groups.Request().Select(x => new { x.Id, x.DisplayName }).GetAsync();
