UniversalIDE
Add-on based IDE adaptable to any developement platform
UniversalIDE is an open source development environment studied to be compatible with any programming language thanks to its add-on based structure. Anyone who knows the .NET Framework can develop add-ons to support a programming language, defining syntax highlighting rules and interfacing the IDE with compilers or interpreters. It is written in Visual Basic .NET, so it requires the .NET Framework to run.
