Start 3Ds Max from C# .NET application and then send commands to it

Question

I am trying to start 3Ds max from a C# .NET application and send commands to it. I can start it as a process and send a starting command but then I don't have full control over sending commands and receiving outputs.

I am intermediate level in MAXScript and beginner in C#

Last thing I tried was with this code:

using Autodesk.Max;

IGlobal global = GlobalInterface.Instance;
IInterface14 coreInterface = global.COREInterface14;

But it also won't start max.

I assume that correct way is to Autodesk.Max and start from there, but I just can't find right documentation for that, searched in SDK too.
