   * Instructions: This sample can be run using either the Azure Storage Emulator that installs as part of the Microsoft Azure SDK, which is available in Windows only - or by  
   * updating the app.config file with your connection string.
   *
   * To run the sample using the Storage Emulator (Microsoft Azure SDK)
   *      Start the Azure Storage Emulator (once only) by pressing the Start button or the Windows key and searching for it
   *      by typing "Azure Storage Emulator". Select it from the list of applications to start it.
   * 
   * To run the sample using the Storage Service
   *      Open the app.config file and comment out the connection string for the emulator ("useDevelopmentStorage":true) and
   *      set the connection string for the storage service.
   *
   * Note: The Shared Access Signature sample currently does not work with Emulator for a well know issue in the azure-storage library. If you are planning to run
   * this sample, please use the Storage Service.
