WinUI3:What is the right way to create and initialize UIElement Programatically with C++/Winrt

I'm trying to bring up the WinUI3 window programmatically with c++/winrt. To bring up the first window, I created a Window variable and activated it, Like this

using namespace winrt::Microsoft::UI::Xaml::Controls;  

Window SampleWindow;  

By this, I was able to bring up a window, my concern here is, is this the correct way to initialize a window and activate it[Programatically]? I could not find any official documentation for Initializing UIElement programmatically with C++. So is this the right way to do it?

    Hello @Harshithraj1871
    Welcome to Microsoft Q&A!

    Your code is ok.

    You can refer to the example of Window Class, and the startup method of MainWindow.

    winrt::Microsoft::UI::Xaml::Window window{ nullptr };  
    void App::OnLaunched(LaunchActivatedEventArgs const&)  
        window = make<MainWindow>();  

    Thank you.
