I am hosting my application on Azure appservices. and have upgraded to Umbraco 7.7.2 today. But then I cannot find the umbraco.config

I am not sure what could be wrong, specially that after updating Umbraco I had to reinstall my packages (even Usync) in order for them to work.

I've looked at my App_data folder and in my Azure blobs. Am I missing something? what could be wrong?

In filesystemproviderconfig I have a transformation to use Our.Umbraco.FileSystemProviders.Azure.AzureBlobFileSystem.

<FileSystemProviders xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <Provider alias="media" type="Our.Umbraco.FileSystemProviders.Azure.AzureBlobFileSystem, Our.Umbraco.FileSystemProviders.Azure" xdt:Transform="Replace" xdt:Locator="Match(alias)">
    <Parameters>
      <add key="containerName" value="content" />
      <add key="rootUrl" value="https://xxx.blob.core.windows.net/" />
      <add key="connectionString" value="DefaultEndpointsProtocol=https;......"/>
       <add key="maxDays" value="365"/>
    </Parameters>
  </Provider>
</FileSystemProviders>
