I'm writing a language service that is going to use c# intellisense in certain parts of the language. From what I've found out, there should be a service in Roslyn that will give me completion items for c#. However, there's no mention of this in the official documentation so I'd like to ask, how do I go about using the intellisense service from my own VS Extension?
I tried what's described here http://social.msdn.microsoft.com/Forums/en-US/roslyn/thread/78e6f820-8f9f-4da9-8a47-d46f846b0a11 , with no success though. My guess is that this info is out of date (since Roslyn is still in development and the aforementioned thread is from 2011).
