Editor.NET 2.5

Editor.NET is an advanced syntax code editor allowing integration of a highly flexible edit control in your .NET applications.

Editor.NET has almost all the features that can be found in the Visual Studio.NET code Editor, including customisable syntax highlighting, code outlining, code completion, unlimited undo/redo, bookmarks, word wrap, drag-n-drop, built-in search/replace dialogs, multiple view of the same text, displaying gutter, margin, line numbers and many more.

Editor.NET is available in WinForms and WPF editions.

New: Editor.NET 2.5 is fully compatible and tested with Visual Studio 2015; it includes of C# and VB.NET parsers based on .NET Compiler Platform ("Roslyn")  official release, which provides open-source C# and Visual Basic compilers with rich code analysis APIs.

Employing these APIs allows advanced code-editing features, such as code completion, finding references and declarations, code outlining and highlighting syntax warnings and errors, to be equivalent to Microsoft Visual Studio code editor.

"To create a really good code editor is not an easy task (frankly speaking, the task is rather HARD), there are many non-trivial things, like complex syntax highlighting, code folding, context hints (IntelliSense, AutoComplete) and a bunch of others. Fortunately, through the programming history, there are some people who have already gone this way and provided a complete and consistent solution to the problem: Editor.NET from Quantum Whale.
