title: Use Azure for desktop application log
body: <p>I have an 'offline' WPF application that I want to release to users. 
  It was not using any cloud technologies, but I want to start using it - for now, for user registration, application logs and updates.</p>
  
  <p>Currently, I have the application log designed with StreamWriter to a local file on the user machine.</p>
  
  <p>I would like to stop using a single local log file for each machine and rather have all instances of my WPF app to append the same log file in Azure.</p>
  
  <p>I already have an azure account and a simple database there for registered users and a blob for the updated app download.</p>
  
  <p>But what is the best approach for creating and appending a text file? My main concern is performance and reliability - I don't want this to make ma app slower and less stable.</p>
  
  <p>Thanks
  Bartek</p>
