One of the tools I use for development is Code Compare from Devart, which allows me to easily and efficiently compare source code, whether it’s a file or a folder comparison. This tool rocks and they have a free version to boot!
Ok so what is Code Compare?
Code Compare is a free tool designed to compare and merge differing files and folders. Code Compare integrates with all popular source control systems: TFS, SVN, Git, Mercurial, and Perforce. Code Compare is shipped both as a standalone file diff tool and a Visual Studio extension.
Code Compare introduces the concept of Code Orientation, ultimately making it stand out from competitive file diff software. The concept implies syntax highlighting, similar lines detection as well as unique structure and lexical comparison algorithms. The file compare tool takes into account language specifics, which allows comparing sources in several of the most popular programming languages as code!
Integration with TortoiseSVN
One of the great benefits about Code Compare is that it can be integrated with a number of version control systems. This means you’re not stuck using the comparison tool that comes with each version control system and you can have a consistent experience across all your comparisons.
I have Code Compare integrated with TortoiseSVN and TFS.
