The Visual C++ compiler is unable to find a public parameterless constructor when attempting to externally consume a class that references itself within multiple generics. The error does not appear using C#. The class library builds successfully. Visual C++ app results in a C3392 error, while C# app builds successfully.

I have been unable to figure out a workaround.

Hi: this issue has been fixed. The fix should show up in a future release of Visual C++.

Thank you for reporting the issue.

Using getter/setter methods directly in place of the property 'p' does seem to work around the issue. I tried this technique in my actual project with successful results. Thanks. This isn't preferred, but should allow me to move forward.

Consider an ordinary getter instead of property 'p':

    public ref class C
        C() { }

        A<B<C^>^>^ get() { return nullptr; }
