title: Reverting back to a specific changes after saving in Visual Studio 2019
body: <p>In my project in Visual Studio 2019, I opened a file and made some changes. After running it, I decided to undo(ctrl + z) my changes and revert it back to the original point where I opened it and do some other code again to verify my changes. After saving and running my code, I decided to revert it back to the point where I made my first changes. And now, I cannot revert it back anymore. I tried to search it online but had no luck. Is there a way to revert my first changes back? Thanks in advance for your help.</p>
