Visual Studio adding prefix to stated namespace

Question

I'm getting a few:

'The type or namespace 'blah' does not exist in 'A.B.C' (are you missing an assembly reference?)

The code looks like:

namespace A
{
   using B.C;

   public class Blah()
   {
      //...
   }
}

A and B are both assemblies that are included in the solution. Both use .NET 4.0. Assembly B does in fact have a namespace C. Assembly B is included as a reference in assembly A.

Why is it looking for A.B.C when the reference is B.C?

Would you mind providing a complete example with a skeleton for all the assemblies in question? Also, what line exactly is causing the error? — devuxer, Oct 03 '13 at 20:08

@DanM, thanks... Eric's answer on that questions got me thinking about the problem differently enough that I could solve it. — Robert Gowland, Oct 03 '13 at 20:31

The problem was a typo in a different file than the ones with errors.

In another file I had:

namespace A.B.C
{
//...
}

I must have done an accidental Ctrl-P at some point?

The steps I took to find the offending file:

Open up the most recent file that I had changed
Examine the namespace
Repeat with the next most recent
