Is there a method / system / program to keep track of different stages and changes in writing the code for a project?

Question

Forgive me, but I don't know the technical term to know what to search for.

I am trying to find a way to keep track of changes in my code during the development of my program. something that would allow me to go back to a section of code that I deleted. I am not talking about "undo". But rather a way that would let me keep track or be able to retrieve a section of my code that I deleted but now want it back.

Is there such a way? If there is, then what is this whole system/procedure called? Is there something that integrates with Visual Studio 2010?

Answer 1

you could use

SVN or GIT

but for local use, I would prefer SVN. its free and its easy. For visual studio there are a few SVN client plugins (like VisualSVN). But, I would suggest TortoiseSVN as the client.

To be clear, SVN is the server, TortoiseSVN is the client. (Both are free open source tools)
