I have never seen this before and have no idea what it causing it.

When I put a breakpoint at the end of code below, the elapsedSeconds variable is NOT listed in the locals window. If I try to Watch it, the Value = "The name 'elapsedSeconds' does not exist in the current context". How is that possible???

public ActionResult Index()
{
    Stopwatch sw = Stopwatch.StartNew();

    var userID = WebSecurity.GetUserId(User.Identity.Name);

    var model = ModelHelper.GetModel(userID);

    long elapsedSeconds = 0;
    elapsedSeconds = sw.ElapsedMilliseconds;

    return View(model);
}

    Has it been optimised away in a Release build, because it has no effect? – RichieHindle Jan 25 '13 at 13:38
  • Holy Crap.... to my defense it is early in the morning and I haven't had my coffee. Thank you @RichieHindle. For anyone who stumbles across this... I just needed to switch my build configuration back to debug... duh. – SLoret Jan 25 '13 at 13:45

Select 'Code Optimization' property as "Disabled" in Project property window, in case you want to take a look at the value. It's the compiler optimization process, that renders evaluating that variable unnecessary.

    It is good to disable optimizations in Debug Configuration. In case of Release Configuration by default it is "Maximize Speed" – Vinod T. Patil Apr 13 '15 at 11:08

I got this too in a Web project. Neither restarting Visual Studio or any other solution in this thread sovled it.

My solution was to restart IIS. After that I rebuilt the project and started it and got locals to work again.

Rebuilding the solution helped in getting the variable hover feature back.
