Hello World example for .NET

[Alex Smith]

Hello all. 

I have read the language guide and tutorial for the language in my use case (C#). So far, everything I've read has made sense in isolation. 

My confusion begins in trying to place PBF in the wider context of C#/.NET project. For instance, I have a few questions:

• How do I return PBF to the client?
• How do I read in PBF from the client?

Based on those questions, does anyone have a very simple "Hello World" example for C#? It doesn't need a lot, just sending/receiving PBF.

Thanks in advance.
