ClientSecretCredential, The method or operation is not implemented error

Question

Hi

I am trying to get a MS Graph to read some documents from SharePoint. This needs to be done without a user being logged in. I am using code below at the end to do so. I have created app and client secret in Azure AD. However when I run below code I get a 'System.NotImplementedException: The method or operation is not implemented' error on line;

var clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret, options);

What am I missing?

Thanks

Regards

   var scopes = new[] { "https://graph.microsoft.com/.default" };

   var tenantId = "...";

   var clientId = "...";
   var clientSecret = "...";

   var options = new TokenCredentialOptions
   {
       AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
   };

   var clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret, options);

   graphClient = new GraphServiceClient(clientSecretCredential, scopes);

Hi @-- --

Try this:

string[] scopes = { "https://graph.microsoft.com/.default" };  
  
IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder  
                            .Create(clientId)  
                            .WithTenantId(tenantID)  
                            .WithClientSecret(clientSecret)  
                            .Build();  
  
ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication, scopes);  
  
GraphServiceClient graphClient = new GraphServiceClient(authProvider);
