The F# team at Microsoft Research and Microsoft are currently working hard towards our planned CTP release of F#. This is a follow up to the 1.9.4 release of F# as a research language.
When it comes, this release will be the first release that includes signficant improvements in the Visual Studio tools. Brian McNamara has been posting a few sneak screen shots of the project system in Visual Studio. Watch Brian's blog for more!
The project system isn't the only thing we're doing: we've done an end-to-end design review, some results of which appeared in 1.9.4, we've got improvements to F# Interactive in Visual Studio, and there are other improvements across the board, as well as some great new productivity features. We look forward to your feedback when we role this release out, and we know it will make your use of F# more productive still.
