    <p>So I am just trying to list the tables in the storage account to test the authorization using the <a href="http://msdn.microsoft.com/en-us/library/windowsazure/dd179405.aspx" rel="nofollow">Query Tables</a> method. I tried using the SDK, but the SDK was trying to reference DLLs that aren't available in RT. Decided to try out the REST API. but am having trouble with the authentication from this spec <a href="http://msdn.microsoft.com/en-us/library/windowsazure/dd179428.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windowsazure/dd179428.aspx</a></p> <pre><code> public async Task ExecuteAsync() { try { HttpClient client = new HttpClient(); Dictionary&lt;string, string&gt; headers = GetHeaders("/Tables"); client.DefaultRequestHeaders.Date = DateTimeOffset.Parse(headers["Date"]); client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("SharedKey", headers["Authorization"]); const string url = "http://account-name.table.core.windows.net/Tables"; XmlReader reader = XmlReader.Create(await client.GetStreamAsync(url)); // // Do some stuff with the reader here // } catch (Exception e) { // handle exception } } public Dictionary&lt;string, string&gt; GetHeaders(string resource) { Dictionary&lt;string, string&gt; headers = new Dictionary&lt;string, string&gt;(); headers["Date"] = DateTime.Now.ToString("R"); headers["Authorization"] = GetAuthorizationHeader(resource, headers["Date"]); return headers; } public string GetAuthorizationHeader(string resource, string date) { const string key = PRIMARY_KEY; const string accountName = ACCOUNT_NAME; string signee = string.Join("\n", new List&lt;string&gt; { "GET", "", "", date, resource }); // make the signature MacAlgorithmProvider hmac = MacAlgorithmProvider.OpenAlgorithm("HMAC_SHA256"); IBuffer keyMaterial = CryptographicBuffer.ConvertStringToBinary(key, BinaryStringEncoding.Utf8); CryptographicKey hmacKey = hmac.CreateKey(keyMaterial); IBuffer data = CryptographicBuffer.ConvertStringToBinary(signee, BinaryStringEncoding.Utf8); IBuffer hash = CryptographicEngine.Sign(hmacKey, data); string signature = CryptographicBuffer.EncodeToBase64String(hash); return string.Format("{0}:{1}", accountName, signature); } </code></pre> <p>Obviously I am missing something as I continue to get 403's. See any problems looking through this code?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
