I'm trying to create azure storage using follwing simple code.
Tried manually for cross check working fine manually.
static void Main(string[] args)
{
    //Parse the connection string and return a reference to the storage account.
    CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));
    //Create the blob client object.
    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
    //Get a reference to a container to use for the sample code, and create it if it does not exist.
    CloudBlobContainer container = blobClient.GetContainerReference("sascontainer");
    container.CreateIfNotExists();
}
getting error :
An unhandled exception of type 'Microsoft.WindowsAzure.Storage.StorageException' occurred in Microsoft.WindowsAzure.Storage.dll Additional information: The remote server returned an error: (407) Proxy Authentication Required.
