Thanks!

Excellent. I've been using Roslyn at SymbolicComputation.com for my Sym project so I'm glad to see you're moving forward with it.

It seems like Roslyn setup picks up the VS2010 shell installed by SQL Server 2012 and refuses to install since no VS2010 sdk is present, even though I only have VS2012 RC (and sdk) full installed on my system.

@Scott Brickey:

Roslyn does provide extensibility, but not for all of the scenarios that you mentioned. Changing or adding syntax to the C# and Visual Basic languages is not supported by Roslyn. However, you can build extensions to the C# and Visual Basic editing experiences using Roslyn. For example, you can create extensions for the source code formatting engine, for the syntax highlighter, the statement completion list, etc. You can even create new refactorings and quick fixes. For an example of creating a Roslyn extension, check out the "How to Write a Quick Fix" walkthrough.

C#: msdn.microsoft.com/.../hh543922

VB: msdn.microsoft.com/.../hh543921

@vtp: Do you have the VS SDK 2012 RC installed? The Roslyn CTP won't install without the VS SDK, though the installer should have provided you with a link to download it. www.microsoft.com/.../details.aspx

any idea if the Roslyn extensions extensible for VS add-ins? (maybe adding additional language support, adding syntax, changing formatting, etc?)

I don't have VS2010 only VS2012RC install on my test win8 machine it won't install.

@bartsipes:

For now, the Roslyn project is specifically targeted at the C# and VB languages. While any language can draft from the Roslyn APIs to create a similar object model, there isn't an active effort to do this for F# at the moment. That said, F# has a compiler written in managed code (i.e., in F#) with source code drops available at fsharppowerpack.codeplex.com.

@Mr. S: When installed, the CTP adds the following to your primary Visual Studio install:

1. The C# Interactive Window

2. Project Templates for creating Roslyn extensions

3. Editing support for .csx (i.e. C# Script) files

4. Reference assemblies for the various Roslyn assemblies in the Add Reference dialog

Installing Roslyn *does not* replace the C#/VB compilers or IDE experiences in Visual Studio. So, you can continue to use VS to develop software.

Note that installing Roslyn *does* create a special instance of Visual Studio which replaces the C# and VB IDE experiences. However, that instance is only used when debugging Roslyn extensions that you create.

How much of VS2010 does the Roslyn CTP "replace"? I ask because I'd love to have the C# Interactive window, but don't want to affect my actual code/output.
