Microsoft “Roslyn” CTP's, get the CTP, Whitepaper and Walkthroughs...

Microsoft Downloads - Microsoft “Roslyn” CTP

"The Microsoft “Roslyn” CTP installs as an extension to Visual Studio 2010 SP1. “Roslyn” is a long lead project which we are considering for the post-Visual Studio 11 timeframe. The CTP includes an early preview of the APIs exposed by the C# and Visual Basic compilers, and the Interactive window experience.



Traditionally, compilers are black boxes -- source code goes in one end, and object files or assemblies come out the other end. The Roslyn project changes that model by opening up the VB and C# compilers. The compilers provide APIs to allow tools and end-users to share in the wealth of information the compilers have about code. The Microsoft "Roslyn" CTP previews the new language object models for code generation, analysis, and refactoring, and the upcoming support for scripting and interactive use of C# and Visual Basic.
The CTP installs the following items:

  • Visual Studio Project Templates
    These project templates help you get started using the Roslyn APIs and building new Visual Studio extensions.
  • Reference Assemblies
    The Roslyn assemblies that can be added to projects via the Add Reference dialog.
  • C# Interactive Window
    A new tool window called C# Interactive is available in Visual Studio by invoking View -> Other Windows -> C# Interactive from the menu. You can explore by executing snippets of code in the C# Interactive tool window, cumulatively building up execution context as you experiment. In addition to typing directly into the tool window, you can also select code in C# and C# Script (.csx) files and invoke "Execute in Interactive" or "Copy to Interactive" from the context menu.
  • C# Script File Editing Support
    C# Script (.csx) files allow top-level statements much like the C# Interactive window. You can create a new C# Script file by invoking File -> New File -> > Script -> Visual C# Script from the Visual Studio menu. C# Script editing features like IntelliSense are powered by the Roslyn Language Service.

Please note: This is a technology preview and there are known limitations. While the shape of the public API surface is complete, only a subset of the C# and Visual Basic languages have been implemented at this time in the current CTP.

Roslyn is a complete rethink/rework of the C# and VB.Net compilers, written in C# and VB.Net. When this ships it will allow for development/IDE features we've only dreamed of (or that are today really really really hard to do and so only a few third parties do them...)
