Text diff visualization control for WinForms or WPF

Question

In continuation of the my previous question, are the any good controls for text diffs visualization?

Something like StackOverflow's revision diff viewer but for WinForms or WPF

Requirements:

• free, preferably open-source
• based on WPF or WinForms

No apps please, only components.

I'm not interested in OSS diff tools

Answer 1

I never heard about a specific .NET component for diff visualization (it's kind a niche), but perhaps you could rely on advanced editor to build your own without too much trouble.

Syncfusion proposes a complete component suite dedicated to text/code edition, with a lot of built in features that you might find useful :

• Line and selection background
• Text highlighting (colored underline, waveline, borders, strike, etc.)
• Selection margin
• Text selection
• Syntax highlighting

Important note : it is not free.

Answer 2

There is (as part of GitSharp) an open source diff engine in c# with a very easy to use API and (as part of GitSharp.Demo) a WPF diff viewer. The code should not be too difficult to extract from the project.

might also want to take a look at MeneesDiffUtils. Has a bunch of diff related utils including a visualization control. Full source code provided and is under a license called CharityWare.
