\bin\netduino.helpers.dll not found

Hey, I took my old Netduino 2 out the other day for the first time in a long time and was trying to test it out with the ST7565 GLCD. I downloaded the helpers from https://github.com/bleroy/netduinohelpers and tried to deploy the Adafruit7565Test program to my netduino.
I had just updated the firmware to 4.3 as well as the SDK but every time I try run it, the error comes up: …\bin\debug\netduino.helpers.dll not found. And it’s not there.
Are the helper files actually missing a crucial file or am I suppose to do something to establish that .dll?

Setup:

Netduino 2 .net MF 4.3, VS2015, Win10
LCD: ST7565r

Cheers!
