Sample code

Case 1:

Steps to Reproduce:
1.  Set a breakpoint on line 27 of Program.cs - 'Console.WriteLine(s);'
2.  Debug the program
3.  When the debugger breaks at the line, hover over the variable s to inspect it's value

Expected Result: s has a value of "Hello from Bar"

Actual Result: Hovering over 's' displays "string s", local variables has no variable s, and if s is set as a Watch variable, it displays as "The name 's' does not exist in the current context".

Inspection works fine in non-async methods, for instance breaking on line 17 and inspecting the value of z after the call to 'int z = BarMath(1).Result'

Looks like the CorDebugger needs to include hoisted variables in the locals
Comment 2 Marius Ungureanu 2013-09-08 07:43:20 UTC
Aside from having to step multiple times (will fix this), this issue is fixed and will be included in future releases.
Comment 3 Sadik Ali 2014-03-31 05:56:53 UTC
I have verified this issue. I debug attached project and followed steps mentioned in bug description and noticed that when I am mouse hovering over 's' getting same Actual result as mentioned in bug description.

Hence I am reopening this issue.
