title: Windows Azure: length of blob remains 0
body: <p>I'm confused about how to get size of the blob in Windows Azure.</p>
  
  <p>In my case, I first get the blob reference with <code>CloudBlockBlob blob = container.GetBlockBlobReference(foo);</code>(here foo is name of blob and I'm sure the blob exists). Then I try to get blob size <code>blob.Property.Length;</code> However, it always return <code>0</code>. I breakpoint at this statement and track content inside <code>blob</code>: <code>uri</code> of the blob is correct, can I infer that the blob is correctly retrieved from that? While all the fields in <code>Properties</code> is either <code>null</code> or <code>0</code>. I cannot figure out a solution. Is it because I currently emulate the app locally in <code>Storage Emulator</code> and will be OK after the deployment?</p>
  
  <p>Thanks and Best Regards.</p>
