title: How to generate a new .pfx file after being lost from source control?
body: <p>I'm using GitHub to host an open-source Windows 10 app I'm developing. I accidentally gitignored my app's PFX file, so when I deleted my local copy and re-cloned the repo, I was left without a <code>MyApp_TemporaryKey.pfx</code> file. Now Visual Studio is complaining about this, and I'm unable to build the solution.</p>
  
  <p>How do I regenerate this file so I can run the app again? Thanks for helping.</p>
