Question

I get an exception every time I try to create a container for the blob

using the following code

---

CloudStorageAccount storageAccInfo;
CloudBlobClient blobStorageType;
CloudBlobContainer ContBlob;

blobStorageType = storageAccInfo.CreateCloudBlobClient();

//then I initialize storageAccInfo

ContBlob = blobStorageType.GetContainerReference(containerName);
//everything fine till here ; next line creates an exception

ContBlob.CreateIfNotExist();

Answer 1

My guess is that the container name you’re using violates the naming rules. Check http://msdn.microsoft.com/en-us/library/dd135715.aspx.
