C++ namespaces and VS.Net

I'm a bit unsure on how you're "supposed" to work with namespaces in C++. Say, you have a headerfile declaring a class inside a namespace, something like this: namespace foo { class bar { void somefunction(); void someotherfunction(); } } So far so good. But is there a "proper" way to write the corresponding cpp file? So far, I've wrapped those into namespace foo { } as well: namespace foo { void bar::somefunction(){ } void bar::someotherfunction(){ } } But Visual Studio 2k5's Intellisense can't figure that out. It doesn't recognise class members. (Still compiles ok though) So that made me wonder, am I doing it "wrong"? I can think of two alternatives. Either specify the full namespace on every function in the cpp file, like this: void foo::bar::somefunction(){ } But that seems a bit verbose. Doesn't exactly help with code readability. Or alternatively, just put a "using namespace foo" at the top of the cpp file. But that doesn't seem a very elegant solution? I thought blanket "using namespace ..." statements were discouraged? Anyone know what the "proper" way to do this is?
