Lambda Text Editor (formerly ZetaWord)
A Notepad replacement for Windows. It's better than Notepad in some ways, worse in others. It was originally released at http://zetacentauri.com and was downloaded more than 8000 times before being open sourced.
A compiled, installable version of ZetaWord is available in the installer directory:
https://github.com/Xangis/ZetaWord/blob/master/installer/ZetaWord1.05Setup.exe
ZetaWord is written using C# and .NET 2.0. It builds and runs on Windows and also works on Linux via Mono. A project is included for Visual Studio 11. It doesn't have any complicated dependencies, so you can create a project for an earlier version simply by including the source files.
Installer scripts for InnoSetup and NSIS are included, but you'll probably have to modify the paths in order for them to work since they're probably specific to my development environment.
Development Status
This application is no longer actively maintained, and I'm unlikely to accept pull requests. It was more of an experiment to build a basic text editor using C# than a serious product. It's great if you find it useful, but you should download LibreOffice instead.
