Intellisense doesn't work in Visual Studio 2012 + WebExtensions 2.5.1

There is no member auto-completion after . (dot) or ctrl+space or ctrl + j etc.
Without these, I'm going to hate TypeScript at all!

I am having the same issue with my Visual Studio install.

I tried a clean install of Visual Studio in a VM and only added the TypeScript add-on and things appear to be working properly.

Is there a way to detect if there is a conflict between the TypeScript language services and another plugin?

To be clear, I am experiencing this problem with the default content in a new TypeScript file in Visual Studio.

At the bottom of the script, there is the following content:
// Local variables
var p: IPoint = new Shapes.Point(3, 4);
var dist = p.getDist();
When I type "p." I do not get the intellisense popup with methods and properties. I do get the type tooltips when I mouse over the Shapes and Point references in line 2 of the sample above.

Additionally, I've tried running Visual Studio in SafeMode
devenv /safemode

and found no success either.

We're working on tracking down what might be causing this issue. If you can provide more information (what plugins are installed, are you running a VS CTP, etc) that would be helpful. If you also happen to track down a workaround, we can use that to inform what's going on as well.

One user reported having success by running repair on the VS 2012 install (Add Remove Programs - Visual Studio 2012 - Repair). After this, Intellisense seemed to work again. If you get a chance to try this, I'd be curious to see if this clears up the issue you're seeing.
