Need Examples using USB-8452 with C#

I would like to use the NI USB-8452 with Microsoft C# and Visual Studios 2013.

I found the  NI Knowledge Base paper: "How Can I Access USB-845x API Function from a C/C++ Program?"

 http://digital.ni.com/public.nsf/allkb/F997E364CFAA63F6862573540064C028

Although This was very helpful, I am still having trouble converting it to C#.

Does anyone have any examples, specific to C#, that they can share with me?

Thanks,

Ken
