Consume a C# component with WinUI 3 controls from a Win32 project

[Iordan-Iulian-Bogdan]

Hello, I followed this tutorial https://learn.microsoft.com/en-us/windows/apps/develop/platform/csharp-winrt/create-winrt-component-winui-cswinrt and I would like to do the same thing but from a Win32 project and I am stuck.

I have a Win32 application which can create WinUI windows by loading an xbf file, the problem is that I want to use a datagrid custom control which is only available for C#, this works fine when I use it from a WinUI C++ application but I don't know how to get this working from within a Win32 app.

For instance in my c++ app I can add the datagrid like so in MainWindow.xaml.cpp:

    MainWindow::MainWindow()
    {
        InitializeComponent();

        m_reporter = winrt::WinUIComponentCs64::NameReporter();
        myGridContainer().Children().Append(m_reporter);
    }

NameReporter is a custom control which contains a datagrid.

I went through the same steps like in the tutorial for my Win32 app but this line : m_reporter = winrt::WinUIComponentCs64::NameReporter(); crashes my app, it complains about something related to CoreMessagingXP.dll but I don't know how to fix it, I am sure something is not configured properly,
