namespace issues

Question

i'm working on a project and i've stumbled on an annoying issue. say i have a file that belongs to a namspace Foo. and then another file that belongs to a namespace Bar. Foo is my main file and it has a line at the beginning which attempts to include the Bar namespace. namely using Bar; however i get the following on compiling: error CS0246: The type or namespace name 'Bar' could not be found (are you missing a using directive or an assembly reference?) whats going on here? i know this is possible in theory. havent seen any practical code that used it though....would i have to have some sort of compiletime flags added or put everything in the same file or something?

nope. That works if you are using a simple compiler as you can reference them but in VS they have to be in the same project. Otherwise when it compiles it does not reference the other file.

must they be in the same project? can i not just have two files in the same directory and let one use functions in the other?

if the namespaces are in different projects then you will have to add a reference to the namespace Bar via the project properties section in Visual Studio.
