Hello!
My understanding of this task is that I will implement some C# interfaces to allow users to indirectly call some C++ DLL functions.
Fortunately, I have done a similar job. I wrote the camera SDK function (VC2010, C++, DLL), which implements network control and data reception for the camera, and provides the client C# Winform example to call my SDK. If you are considering a similar work task, then this is within my ability.
Working time is usually difficult to estimate, depending on the number of C++ interfaces, specific details, you need to send me a specific interface to know.
I am honest. When I find out that your task is more difficult than my ability, I will inform you immediately and give my advice.
Thanks in advance!
