Save your Project

[Derek5885]

As a newbie I learned the hard way that you need to make a folder where you make a copy of your project. I make daily copies. I made a mistake and I was left with dozens of errors and without a working copy had to start all over. Although this may seem obvious for some it was not for newbies like me.

You should save often on anything you do.

You probably didn't have to start over. I'm sure you could have recovered.

You should look into using git in Visual Studio with your project.  You can save yourself having to make complete copies of your project as backups.  You can easily undo changes, view history of changes, compare changes at different points, etc.  It's a very powerful tool.
