Hi Suryansh,

you can call methods in unmanaged dlls using standard Interop methods (see PInvoke for a lot of examples). However the limitation is that only primitive data types can be coerced across the managed/unmanaged boundary. So you'll need to create a C++ SDK that can be used with purely primitive types. This is what we do with RhinoCommon btw. The Rhino SDK is not 'pinvokeable', so we create a pure C++ dll that exposes native Rhino SDK methods and classes in such a way that we can call them from the C# part of RhinoCommon.
