Do you have a C# example that's easier to understand, something that doesn't require a wrapper?

Hi, I'm writing some simple code in C# using visual studio to read the channels on a model 2206B oscilloscope. When I try to add a reference to PS2000a.dll, MVS gives the following error message: A reference to 'C:\Program Files (x86)\PicoTechnology\PicoScope6\PS2000a.dll' could not be added. Please...
