CS-Script Plugin (CSScript.Npp)


Github All Releases

Download latest release

This Notepad++ plugin requires .NET v4.0 or higher.

.NET Framework -> .NET transition

The current release of CS-Script targets .NET Core family runtime (.NET 6).
CS-Script started targeting .NET 5+ about a year ago as .NET Framework further development has been effectively cancelled by the .NET team.

Though Notepad++ CS-Script plugin is still shipped with the engine targeting by default .NET Framework. This is done as a reflection of the fact that many users of this plugin are still relying on .NET Framework.
However the plugin can be configured to use the .NET Core version of the script engine (you can install it from here).
The next version of the pluging will still maintain .NET Framework engine but by default will try to auto integrate with .NET Core. And the next release after that will have the .NET Framework option only available as a manual configuration/deployment step.

Starting from v1.3 plugin delivers full support for VB.NET syntax. More reading...

You can also run scripts targeting .NET 5/Core runtime.

This plugin allows convenient editing and execution of the C# code (scripts). It also allows the usual C# intellisense and project management tasks to be performed in a way very similar to the MS Visual Studio.

In addition to this, it provides generic debugging functionality (with the integrated Managed Debugger) as well as the ability to prepare C# scripts for the deployment packages (script+engine or self-contained executable).

Typically user opens the C# file with Notepad++ and after presses 'Load' button on the CS-Script toolbar the all features can be accessed through two Notepad++ dockable panels Project and Output panel.


Note: the default compiler engine of the plugin is Roslyn. The engine fully supports both C# and VB.NET syntax but there is some usability information for these syntaxes that you may need to be aware of. See C# 7 support for and VB.NET support details.
