what is the state of the “C# compiler as a service ” [closed]

Answer 1

Certainly not C# 4.0. We are just finishing up the last few bug fixes for C# 4.0.

This direction for the toolset is the long term plan, and might never come to fruition. And I don't discuss schedules for unannounced, hypothetical future features.

UPDATE: October 2011

We have just shipped a preview release of "compiler as a service" aka the "Roslyn" project.

We are still not announcing the final ship vehicle; it will be post Visual Studio 11.

Answer 2

It has been released CTP version in the name of Roslyn. You can check it at RosLyn

Answer 3

I'm pretty sure I heard rumours of this being a "between 4.0 and 5.0" item now (a separate library, like ASP.NET MVC)... but I can't remember where I heard that. I certainly wouldn't expect it in 4.0 at this point. Frankly I don't even really know what the phrase means exactly - it could cover a whole range of features.

Answer 4

It's already available in Mono for quite some time.

Answer 5

As of today (19 October 2011), there is a CTP of Roslyn available for download at http://msdn.microsoft.com/en-us/roslyn.

The CTP installs on top of Visual Studio 2010 SP1.
