Lightweight experience

• No IDE
• Any editor will do
• No project
• Package manager
• No namespace, class

Introducing script(cs)

#r "System.Data"
using System.Data;
using System.Foobar; // Roselyn error thrown

#load 'Greeter.csx'

scriptcs .\Greeter.csx
scriptcs -- custom parameters here

Packages in script(cs)

scriptcs --install MongoDb
scriptcs -install // restores everything from packages.config

If packages.config exists, the REPL will autoload all the packages automatically.

Frameworks like Web API and Nancy look for assemblies in the file system, instead of looking in memory.

Everything runs in a single thread by default.

Script packs

• Add reference assemblies
• Add using statements
• Make libraries easier to consume

Script Packs can be loaded from NuGet. Samples:

• ScriptCs.Contracts
• ScriptCs.WebApi

Takes care of some of the boiler plate code and friction.

var webApi = Require<WebApi>();
var server = webApi.CreateServer("http://localhost:8080");

Steps to coding in VS

• Open VS
• Open a new project from EXE
• Add existing csx files
• Right click EXE -> Properties -> set args, path

Hosting script(cs)

code name: feather

Product roadmap. What's next:

• Pluggable CLI commands
• Pluggable REPL commands
• Hosting for popular frameworks
• Mono support
• Script packs as scripts
• More langauges (F#)
• VS integration?
