Naming Convention in c#

The .NET standard from Microsoft is to use Pascal Case for namespaces, public and protected members (basically anything visible to other classes). For private members and local variables, there's a much wider berth to just do whatever you and your team are most comfortable with.

I'd have a look at the slim book called "Elements of C# Style" by Baldwin, Gray, & Misfeldt. The blue book covers naming conventions, and many other aspects of creating consistent, clean, readable code.
