title: Code a File Path that works in both OSX and Windows (dotnet core)
body: <p>I have to save files in my dotnet core application.  I originally developed in windows; but when I ported the code to try developing on a mac, the file path is no longer valid (i.e. "c:\content...").  Is there a way to reference a file path, in my code, that will work in both situations?  We deploy to azure... so the windows file path must there too.</p>
  
  <pre><code>FileInfo fileInfo = new FileInfo("c:\\Content\\SalesOrderOutput\\" + 
        fileName.txt);
  FileStream stream = fileInfo.OpenWrite();
  </code></pre>
