title: Azure Functions - configuration settings returns null when I try to debug locally
body: <p>I have the following code:</p>
  
  <pre><code>    [FunctionName("FunctionValidateDriverRecord")]
      public static async Task Run([TimerTrigger("0 */1 * * * *")]TimerInfo myTimer, TraceWriter log)
      {
          string connString = ConfigurationManager.ConnectionStrings["AssetContext"].ConnectionString;
          string mail = ConfigurationManager.AppSettings["EmailForErrors"];
  </code></pre>
  
  <p>and local.settings.json:</p>
  
  <pre><code>{
    "IsEncrypted": false,
    "ConnectionStrings": {
      "AssetContext": "data source=server;initial catalog=3md_vistracks_sync;integrated security=True;MultipleActiveResultSets=True"
    },
    "AppSettings": {
      "EmailForErrors": "brauncomm@gmail.com"
    }
  }
  </code></pre>
  
  <p><code>connString</code> has value, but <code>mail</code> is null. Why?</p>
