<p>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</p>

<p>Stack.fs</p>

<pre><code>namespace Col

type Stack= 
 ...
</code></pre>

<p>Now I try to include the namespace in Program.fs by declaring</p>

<pre><code>open Col
</code></pre>

<p>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</p>

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.
