C# Wrapper for C++ OpenNI2 Project

I am looking for a C# wrapper for a C++ OpenNI2 project that will integrate C++ code into my C# WPF Application. I have specific requirements and features that this wrapper should have and would appreciate any advice to help improve the functionality, simplify usage, or improve performance of the wrapper. My timeline for this project is 1-2 weeks. I am flexible with the timeline and would be willing to modify it, if required. I look forward to working with you on this project.

Please find the attached VISUAL STUDIO 2017 project attached with the code to wrapp to C#.
