How to preview GDI+ images using Image Watch?

I'm trying to visualize on memory GDI+ images using the Image Watch extension.

I requested support on this feature long time ago directly on the developercommunity it got a lot of upvotes but MSFT just marked it as "under review".

I tried to follow the extension documentation and implement the natvis myself, but i'm not suceeding on get it to work.

A reproducible example:

#include <windows.h>
#include <iostream>
#include <gdiplus.h>
using namespace Gdiplus;
#pragma comment (lib, "Gdiplus.lib")


int GetEncoderClsid(const WCHAR* format, CLSID* pClsid)
{
    UINT num = 0;
    UINT size = 0;
    ImageCodecInfo* pImageCodecInfo = nullptr;
    GetImageEncodersSize(&num, &size);
    if (size == 0)
        return -1;

    pImageCodecInfo = (ImageCodecInfo*)(malloc(size));
    if (pImageCodecInfo == nullptr)
        return -1;

    GetImageEncoders(num, size, pImageCodecInfo);
    for (UINT j = 0; j < num; ++j)
    {
        if (wcscmp(pImageCodecInfo[j].MimeType, format) == 0)
        {
            *pClsid = pImageCodecInfo[j].Clsid;
            free(pImageCodecInfo);
            return 1;
        }
    }

    free(pImageCodecInfo);
    return 0;
}

int main()
{
    GdiplusStartupInput gdiplusStartupInput;
    ULONG_PTR gdiplusToken;
    GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, nullptr);

    HDC hScreenDC      = GetDC(nullptr);
    HDC hMemoryDC      = CreateCompatibleDC(hScreenDC);
    int screenWidth    = GetSystemMetrics(SM_CXSCREEN);
    int screenHeight   = GetSystemMetrics(SM_CYSCREEN);
    HBITMAP hBitmap    = CreateCompatibleBitmap(hScreenDC, screenWidth, screenHeight);
    HBITMAP hOldBitmap = (HBITMAP)SelectObject(hMemoryDC, hBitmap);
    BitBlt(hMemoryDC, 0, 0, screenWidth, screenHeight, hScreenDC, 0, 0, SRCCOPY);

    Bitmap bitmap(hBitmap, nullptr);
    CLSID clsid;
    if (GetEncoderClsid(L"image/png", &clsid) == 1)
    {
        if (bitmap.Save(L"test.png", &clsid, nullptr) != Gdiplus::Ok)
            std::wcerr << L"Failed to save the screenshot." << std::endl;
    }
    else
        std::wcerr << L"Failed to get encoder CLSID." << std::endl;

    // ...
    // cleanups ignored as this code is just for debugging

}

And my current natvis implementation:

Using the natvis above the extension is detecting the local images but it always show them as invalid:

I'm testing on VS22/Image Watch for VS22.

Looking for any help on this issue.
