Hi, I think I broke VisualMicro 1709.6.0 Debug/Build/upload function on VS2017 15.4.0.

It was working until I swapped from an Arduino Due to Primo board whilst still on the same project . I did change the COM port to match primo board before selecting the Debug/Build button and I got an error msg on the Micro Build output window:

Before this action I can confirm VM debug function worked on both boards whilst using separate projects. I don’t think VM liked me swapping boards in the same Arduino Project.
The Release/build/upload works OK, is just when using the debug function.

I have tried to uninstalled/reinstall VM and Arduino IDE but this has not fix the problem, VM debug is given me the same error msg even on the simple "Blink" code. 
Do I need to uninstall/reinstall VS2017?

Please Help

OK thank you, looking forward to Primo board support.
