csx

A super simple C# script runner for .Net Core with debug and NuGet support.

Installing

choco install csx --source https://www.nuget.org/api/v2

Visual Studio Code

Intellisense for C# script files is provided by OmniSharp

There is still an open pull request that enables intellisense for scripts with NuGet references.

Until that PR gets merged, download this prebuilt version of OmniSharp that you can use to enable this functionality.

Note: Any editor can be used to edit script files, but we need VS Code to be able to debug.

Windows

Simply extract the OmniSharp.zip file anywhere on your drive and update VS Code settings.

{
"omnisharp.path": "PATH_TO_OMNISHARP_FOLDER/Omnisharp.exe"
}

Hello World

Create a new folder somewhere and from within that folder issue the following command.

csx init

This command creates 4 files

Name
.vscode/tasks.json	Enables the script to be executed within VS Code.
.vscode/launch.json	Configures script debugging
omnisharp.json	Enables NuGet references in scripts (Intellisense)
helloworld.csx	A minimal script that outputs "Hello world!" to the console.

Note: Only the actual script file is needed for script execution. Other files are just for VS Code awesomeness.

Running the script

Command Line

csx helloworld.csx
Hello world!

VS Code

Ctrl+Shift+B or "Debug->Start Without Debugging "

Debugging

Set a breakpoint anywhere in your code and hit F5

NuGet

In addition to referencing other scripts using the #load directive we can also reference NuGet packages.

#r "nuget:AutoMapper,6.0.0"
