Devart has recently released new versions of its CodeCompare tools. Taking the specificity of programming languages into account, improved versions of Devart diff tools are designed to fit the needs of developers.
The free CodeCompare 2.50 provides improved basic code comparison functionality. CodeCompare Pro 2.50 provides advanced professional functionality including Structure Comparison and Difference Explorer, plus three-way comparison and merge functionality.
Both products are distributed as Visual Studio add-in tools and as standalone applications.
