title: Opening a file from a pack URI in WPF
body: <p>I am looking to open a .csv file from the application pack to do some unit testing. So what I would really love is some analog to <code>File.ReadAllText(string path)</code> which is instead <code>X.ReadAllText(Uri uri)</code>. I haven't as yet been able to find this.</p>
  
  <p>Does anyone know if it is possible to read text / bytes (don't mind which) from a file in the pack without compiling this file to disk first? </p>
  
  <p>Oh and btw, <code>File.ReadAllText(@"pack://application:,,,/SpreadSheetEngine/Tests/Example.csv")</code> didn't work for me.. and I am already doing the <code>var app = new Application()</code> trick to make sure I have a pack started up during my unit test.</p>
