MATLAB: Integrating MatLab for C# into visual studio

c

I want to be able to use some MatLab functions to smooth real time data collected from an airplane IMU and GPS during an aerobatic maneuver. I am using C# and the suggestions I have seen for integrating MatLab functions into Visual Studio only relate to C or C++. Is the process as simple as finding the proper DLL from MatLab and integrating it into my environment via a "using" statement? If so where is the proper DLL and if not how do I do this integration.
