WinForms c# Saving checkbox status and then reading it back once the program is opened again

I am making a program that is composed of mostly just Check Boxes. I want to save the checkbox status before the program is closed, and then have the program set the checkbox status as it last was.

I have looked at several questions and answer about this, and I have tried them all. Most of them are pretty old and are using VisualStudio 2010. I have tried using Property Settings, and I have also tried to make a file and then read off of that file and set the CheckBox status to whatever it last was.

I am pretty new to C# so I must be doing something wrong, I would appreciate any help that you guys could give me. Thank you.
