Failing to create blob container from my C# program while using Access Key Connection string.

Question

I started exploring Azure. I set up my Azure account, Resource group, created storage account. I try to create Blob container from my C# program:
I am using 'Connection string' from Storage account Access key to access the Storage account and create the blob container and upload some files.

1.CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["StorageConnectionString"]);

2.CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

3.CloudBlobContainer container = blobClient.GetContainerReference("whatever");

4.if (container.CreateIfNotExists()) {}

The program fails on the 4th line giving me error: The remote server returned an error: (400) Bad Request.
Could someone help me to pass through that? Is it firewall?

Accepted Answer

Please follow this approach:
https://video2.skills-academy.com/en-us/azure/storage/blobs/storage-quickstart-blobs-dotnet

   // Create a BlobServiceClient object which will be used to create a container client  
   BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);  
     
   //Create a unique name for the container  
   string containerName = "quickstartblobs" + Guid.NewGuid().ToString();  
     
   // Create the container and return a container client object  
   BlobContainerClient containerClient = await blobServiceClient.CreateBlobContainerAsync(containerName);

Thank you for your reply.
Perhaps that solution would work in some other environment than mine.
For the time being I am getting the following exception:
Perhaps I need to install the right TLS (whatever it is).
