Description Matt 2013-03-01 08:12:51 UTC
Description of Problem:

When debugger stops at a break point the editor displays a point a level above the breakpoint in the call stack. 

Steps to reproduce the problem:
1. Place a breakpoint. 
2. Run program.
3. Debugger stops at breakpoint.
4. Editor is displaying a point in the call stack above the last frame of the call stack (the last frame is correctly where the breakpoint is).

Actual Results:

Breaking above bottom level of the call stack.

Expected Results:

Breaking at the bottom level of the call stack.

How often does this happen? 

Always with the project I am working on.

Additional Information:

Here is a stack trace reflecting the stack when stopped at the breakpoint (numbers added for clarity):

[0] LightStation.Storage.Temporal.HdfFile.LoadStringVector (path="/vec") in /home/calder/Work/Lightkeeper/lightstation/store/src/csharp/LightStation.Storage.Temporal/HdfFile.cs:999
[1] LightStation.Storage.Temporal.Tests.HdfFileTests.TestStringVector () in /home/calder/Work/Lightkeeper/lightstation/store/src/csharp/LightStation.Storage.Temporal.Tests/HdfFileTests.cs:376
[2] NUnit.Core.Reflect.InvokeMethod (method={Void TestStringVector()}, fixture={LightStation.Storage.Temporal.Tests.HdfFileTests}, args=(null)) in 
[3]NUnit.Core.TestMethod.RunTestMethod (testResult={NUnit.Core.TestResult}) in 
[4] NUnit.Core.TestMethod.RunTestCase (testResult={NUnit.Core.TestResult}) in 
[...] Edited

The breakpoint is in the file referred to in line [0], but the editor is displaying the file in line [1]. The editor is at the right place in the file, as if the Call Stack entry had been clicked.
Comment 1 Jeffrey Stedfast 2013-03-05 16:55:25 UTC
The reason for this is because frame 0 is in library code and either:

1. the library project is not part of your solution


2. you have "Debug project code only" enabled in the debugger preferences

Does that fix it for you?
Comment 2 Mikayla Hutchinson [MSFT] 2013-03-05 21:55:07 UTC
It would be AND not OR.

"Debug project code only" means it only steps into the code of assemblies produced by projects in the solution.
Comment 3 Matt 2013-03-06 06:25:20 UTC
No the code is definitely in the project. I believe it is related to tests, stack [0] in the example is code being tested, and stack [1] is an (Nunit if it matters) test. Nevertheless I unchecked the "Debug project code only" and will keep an eye on it.
