using an object in one CLR project / namespace in another CLR project

[James50]

I have one CLR Class Library which defines an ObjectThing


namespace ObjectThing {

public ref class ObjectThing
{
private:
long m_lOrderNo;
public:
ObjectThing();
virtual ~ObjectThing();

virtual property long OrderNo { long get(); void set(long value); }
};
}


and then I have another CLR Class Library which I want to return a list of these ObjectThings.


using namespace System::Collections::Generic;

namespace ObjectFetcher {

public ref class ObjectFetcher
{
public:
static List<ObjectThing^>^ GetObjectThings();
};
}


but ObjectThing is an undeclared identifief in the ObjectFetcher namespace / project.

How do I go about resolving this?
