title: How and where to define an environment variable on Azure
body: <p>I have an ASP.NET MVC web application deployed to Azure. I'm reading my setting using the <code>GetEnvironmentVariable(...)</code> method.</p>
  
  <p>The problem is that I can't find a way to define this environment variable in Azure Portal. Where can I do that?</p>
  
  <p>I don't want to have this stuff in a file. Data that will be there are credentials.</p>
