title: ConfigurationManager.AppSettings[key] not accessible within class library
body: <p>I am unable to access <code>CloudfigurationManager</code> from within an method. The code was originally a klass library and I added a configuration file (<code>App.config</code>) where I am simply adding the values for a hard coded test for Azure SDK. </p>
  
  <p><strong>OpenSessionWithAzure()</strong></p>
  
  <pre><code> private void OpenSessionWithAzure()
      {
          CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSetting["APP_SETTINGS"])// Visual Studio is unable to identify ConfigurationManager
      }
  </code></pre>
  
  <p><strong>App.config</strong></p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;configuration&gt;
   &lt;connectionStrings&gt;
     &lt;add name="StorageConnectionString"   connectionString="DefaultEndpointsProtocol=https;AccountName=userName;AccountKey=Key"/&gt;
     &lt;add name="SasPolicyName" connectionString="myPolicy"/&gt;   
   &lt;/connectionStrings&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>Is there a reason why I am unable to access the <code>ConfigurationManager</code> within my application or a known workaround?</p>
