Visual studio 2012 - locals have disappeared

Question

While debugging VS2012 I have found that I can no longer access variable values:

• The Locals window does not show anything (pictured below).
• The Watch window tells me "Unable to evaluate the expression" for any expression (also pictured below). My personal favourite is that it cannot evaluate true.
• And mousing-over any variable does not show any values tool-tip.

What I've tried:

Restarting Visual Studio

Restarting my computer

Checking that the loaded modules shows debug symbols are loaded

Uninstalling the TeamCity plugin that I installed yesterday

Looking under Tools/Options/Debugging for anything obvious (and disabling other extensions that had been working fine)

EDIT: I've also tried creating a new solution.

I've also noticed that the call stack shows several blank lines where I presume there are supposed to be external method names (pictured above) - I'm not sure if this is relevant, but it is worth mentioning.

Answer 1

I had mistakenly closed the locals window and could not find it as it was not with other windows under the VIEW menu. I found it under the DEBUG menu Windows option.

or Optionally:

Ctrl+Alt+V, L
