I have defined a managed class ( __gc ) and a unmanaged ( __nogc ) in a
separate files (but in the same vc++ dotnet project). I have no problem of
referencing the unmanaged class from the menaged one. My problem is that I
cannot reference managed class from the unmanaged.

In my unmanaged class, if I use "using namespace ManagedNamespace;" I get
error C2871: a namespace with this name does not exist. I get the simmilar
error when trying to reference the Managed class directly from the unmanaged
class methods.

If i use "#include ".\ManagedClass.h" I get syntax errors in that header
file (and it was compiling OK before referencing it from the unmanaged
class).

When I copy the unmanaged class to the same file where the managed is,
everything seems ok. Unfortunately, I must keep them separate.

Can anybody help?

Thanks,
Sasha
