External DLL debugging not working

Hi,

I'm using Unity 5.5.2f1 with Visual Studio 2015 Community.

I have a solution with a class library project and the main unity project.

The class library is set to Unity 3.5 .net Subset Base Class Libraries. I use the post-build event to copy the dll and pdb into an external folder under the main project.

This all seems to be working as I can use classes from the class library in the unity project fine.

However I cannot debug into the class library. I believe I followed the following thread http://unityvs.com/documentation/dll-debugging/ corrrectly. In the external folder of the unity project the mdb has been created as the article suggest.

When i step into the class library (F11) the error I'm getting is:
"
Frame not in module
The current stack frame was not found in a loaded module. Source cannot be shown for this location.
"

Can anyone help?

 

i've had this happen before... I just hit f11 a couple more times and it steps into the code as it should.

can't tell you why *Shrug*
