I think you are referring to WCF? Basically being able to create a model, then operationalize it on the cloud for mass usage?

If so, the good news is that you can do that with RTVS, thanks to the R SDK. Basically you create models locally, test/debug them, then zap that onto Azure ML's backend. The SDK itself isn't tied to RTVS in any way. You can use it from RStudio, Jupyter/R, vim, ... if you like.

R SDK: https://cran.r-project.org/web/packages/AzureML/index.html

Regarding your 2nd question - RTVS/SQL integration - yes, that's definitely coming too. For this initial release we just wanted to make sure we got the core IDE functionality right...
