 <p>You should be fine sharing a single blob container reference as long as you are not trying to perform an update on the container itself (even then, I think it would still be fine in most scenarios like List). In fact, you don't really even need the container reference if you are sure it exists:</p> <pre><code>client.GetContainerReference("foo").GetBlobReference("bar"); client.GetBlobReference("foo/bar"); //same </code></pre> <p>As you can see, the only reason to get a container reference is if you want to perform an operation on the container itself (list, delete, etc.). If you keep the blob references in separate threads, you will be fine.</p>
