What is scriptcs?  OSS project enabling rich C# scripting experience  Script and execute -or- use REPL  Low ceremony, lightweight  Use your favorite text editor  No compilation/projects/solutions scriptcs.net

Key scriptcs features  Relaxed C# syntax & code semantics  As defined in “Interactive C#/VB REPL and Script - Code Semantics Spec“ white paper  REPL  Node.js-like extensibility model (script packs)  Debug & step through in Visual Studio  Sublime text plugin  Scriptcs.Core available as a hostable service  Nuget integration scriptcs.net

Script code semantics  No top level class  No script namespaces  No Main method  Global functions allowed  Script packs accessible through Require<T>  #load directive to load script from script  #r directive to reference an assembly from script  Modules, assemblies loaded automatically/by convention scriptcs.net

Typical C# experience  Need access to source code base  Start Visual Studio (...wait...)  Choose VS project template  Create new solution  Add references, install Nuget packages, import namespaces  Compile and run (repeat: compile+run)  Difficult to distribute code (bloated) scriptcs.net

Typical scriptcs experience  Install Nuget packages with “scriptcs –install”  Write code in any text editor  Run (edit & run)  Easy to distribute code (just CSX + packages.config) scriptcs.net

Extend scriptcs  Script packs   Expose functionality for scripts Modules  Customize scriptcs  Replace any scriptcs internals scriptcs.net
