Is there a way to ⎕NA import a dll exported C++ class in dyalog APL?

Question

I have a .dll which exports a C++ class. Is there some way to use ⎕NA to import this class into Dyalog APL?

I am looking at the DLL Export Viewer, and my class is exporting the way I expect. I have also written a C++ test application which imports the .dll and uses the class, and it functions the way I expect.

// built with default Visual Studio 2019 settings
class __declspec(dllexport) MyClass
{
public:
    void Func();
}

I need an example ⎕NA statement illustrating C++ classes imported into Dyalog APL from a .dll. Something like this:

'MyClass' ⎕NA 'what expression goes here'
mc←⎕NEW MyClass ⍝ or something similar

[]NA is well documented, though it may take some iterations of development to get it working. Consider also trying a plain C DLL first. See also See https://stackoverflow.com/questions/24812963/cross-platforming-c-functions-to-apl/25181286#25181286 — Lobachevsky, Aug 04 '19 at 08:44

Have you read "Name Association" description? http://help.dyalog.com/latest/Content/Language/System%20Functions/na.htm I guess it could help. There are some examples in the end of the article.
