.NET Core script

Installation

To install dotnet-script:

dotnet tool install -g dotnet-script

Creating a hello world sample

copy con helloworld.csx

Console.WriteLine("Hello world!");
^Z

Linux

If you were doing this in Linux or OSX you'll need to include a "shebang" as the first line of the script. This is a standard thing for scripting files like bash, python, etc.

#!/usr/bin/env dotnet-script
Console.WriteLine("Hello world");

This lets the operating system know what scripting engine handles this file.

Nuget

If you you want to refer to a NuGet package within a script (*.csx) file, you'll use the Roslyn #r syntax:

#r "nuget: AutoMapper, 6.1.0"
Console.WriteLine("whatever);

REPL

You can use it as a REPL! (Read Evaluate Print Loop)

C:\Users\scott\Desktop\scriptie>dotnet script
> 2+2
4
> var x = "scott hanselman";
> x.ToUpper()
"SCOTT HANSELMAN"
