I want to write an Editor extension for Visual Studio 2010.
In my extension I want to get information about the Class, method which is at the current caret position.
For example, if I am in an Event Handler and I have some code that shows a MessageBox using MessageBox.show(…) and the caret is at .Show,
I want to query VS Services to get a response which tell me that I the caret is at Show method of MessageBox class which is in System.Windows.Froms.dll version 4.0.40319 etc.
Is it possible?
There is no way to do this with the current APIs in Visual Studio 2010. This is why we’re building the Roslyn APIs so you could. When you install the CTP, we setup a Roslyn instance that replaces the standard language services with the Roslyn ones, and you can ask your question directly to it.
If you don’t want to be dependent upon running in the Roslyn instance (which I assume is the case), then it gets a bit trickier. You can invoke the parsers to understand you’re on a call named MessageBox.Show, but to get the semantics you’d have build up a Compilation making sure you get all the project references and source files right. That’s a far trickier proposition, so depending on your scenario you might want to “cheat” as much as possible.
