I've got some old code on some customer's equipment. The code calls a dotNet control the customer built. This has worked for some years. Now the customer is updating things and has a new control with changes that need updates and recompile. Pretty sure caught everything at this point, but now I'm getting error 4 out of a constructor with the message "Constructor Node " and then the file that the error occurs in. Code 4 shows up as "End of file encountered." in the explain error which is not relevent. My GoogleFu brings up pages about dotNet 2, 3 and 3.5 with post LabVIEW 2013 or dotNet 4 with pre LabVIEW 2013 which doesn't apply to my situation.
LabVIEW: 2015 (compiled)
dotNet version: 4.0 with old control and 4.5.2 with new
