Reference VS2005 assembly from VS2003 project

Is this possible?

I have compiled an assembly in VS2005 and am trying to add a reference to
that assembly from my VS2003 project. The error that I am getting is:
A reference to '{path to vs2005 dll}' could not be added. This is not a
valid assembly or COM component. ONly assemblies with extension 'dll' and
COM components can be referenced. Please make sure that hte file is
accessible, and that it is a valid assembly or COM component.

Do I need to make my VS2005 assembly "COM Visible" and "Register for COM
interop" in order for this to work?

Thanks,
Jody

I have tried making the VS2005 assembly COM Visible and Register for COM
interop, but that did not work.

No, you need to switch to VS2005 / .NET 2.0 for the client too (the
referencing project).

I have not tried this yet, but does it work in the opposite direction where
a VS2005 project references a VS2003 assembly?

I was thinking about taking my VS2003 project and creating an interface for
it, then create a shell EXE in VS2005 to call the VS2003 assembly.

Yes that should work fine.
