Using MSTest and NCrunch for debugging, I cannot hover over variables to see their values. Is this a bug?

Hi, thanks for sharing this issue.

Do you notice this with ALL variables in all methods? Do any of your locals work correctly?

No, it is not for all variables. I hovered over an int[] and I was able to see the values inside, but not for a List<string>. Just to test this issue, I assigned an int named "A" the value of 4. I could not see the value of A by hovering over it.
The way I got to this point is by right clicking on the left margin > Advanced > Debug covering test in existing task runner...

If I use the standard MSTest debugging, I'm able to see all the values of these variables.

This is on Windows 10 Pro, Version 1709, Build 16299.371.

Visual studio:
Professional 2017
Version 15.7.1

NCrunch:
Company Seat License
Version 3.15.0.6

It's possible that this is caused by a metadata issue with the PDBs. Previously, where we've seen these problems it's been related to compiler generated structures such as async/await and yield. If you're able to isolate this problem in code that you can share with me, I can take a closer look to try and understand it better.

Unfortunately, the debugger is a bit of a black box to us. Even when the PDB structure is correct, sometimes weird things can happen in certain environments. Reproducing these problems with consistency can often prove difficult to do.
