Thank you for the sample project!
I've tried to rebuild that project in C# and it seems to me that it works just like the lite-c version.
I've uploaded the project (with a compiled version in the Debug folder)

hmmmm, I wasn't able to see any difference between the lite-c and the c# version frown

get the C# wrapper:
for A7.85.4 and A8.30.4, Version 2.3.9
