This will hopefully be an easy one. I have an F# project (latest F# CTP) with two files (Program.fs, Stack.fs). In Stack.fs I have a simple namespace and type definition
Stack.fs
namespace Col
type Stack=
...
Now I try to include the namespace in Program.fs by declaring
open Col
This doesn't work and gives me the error "The namespace or module Col is not defined." Yet it's defined within the same project. I've got to be missing something obvious
What order are the files in the .fsproj file? Stack.fs needs to come before Program.fs for Program.fs to be able to 'see' it.

I had the same issue and it was indeed the ordering of the files. However, the links above didn't describe how to fix it in Visual Studio 2008 F# 1.9.4.19.
If you open a module, make sure your source file comes after the dependency in the solution explorer. Just right click your source and select Remove. Then re-add it. This will make it appear at the bottom of the list. Hopefully you don't have circular dependencies.
I'm using Visual Studio for Mac - 8.1.4 and i've noticed that some .fs files are not marked as "Compile". You can see this by Viewing Build Output and see if all your files are there and in the correct order.
I've had to manually make sure certain files are marked with "Compile", and have had to move them up and down manually until it "takes".
