Question

I’m a hobbyist programmer and I’ve created an application for my office. Every so often I need to improve the code, add features or fix issues that come up under certain circumstances – I’ve found bugs or ineffective coding even after 3-4 months of heavy usage of the application. The thing is that whenever I modify the code, visual studio saves the changes. This means that if I want to use the program I’ll have to be really fast in coding and debugging or it won’t build – and I won’t be able to use it…
Is there any way to keep the old version of the program without having to save the complete project folder elsewhere? Like creating a new version but keeping the option to go back to the old – working – one…

Answer 1

What you are looking for is called source control.

There are many systems out there, two popular ones are subversion and Git.

Used properly, you will have a full history of each file you have in your project.
