A tabbed control for ScintillaNET to display multiple documents.

The .NET package

The package ending with .NET is depended upon the new Scintilla 5 series Scintilla.NET and is in active development. The other package's Scintilla dependency is no longer being maintained even though the codebase of the dependent software may be maintained.
