The wrong string of code.

Hello,
I found that the next string of code is wrong:
Frame rootFrame = Frame();

This from an another language, I suppose.

This should be:
winrt::Microsoft::UI::Xaml::Controls::Frame rootFrame

Thanks for flagging this. In this case the code is correct as written. In the C++/WinRT tab, Frame rootFrame = Frame(); default-constructs a Frame runtime object — it's the C++/WinRT equivalent of the C# Frame rootFrame = new Frame(); shown in the C# tab. The unqualified Frame resolves to winrt::Microsoft::UI::Xaml::Controls::Frame through the using namespace declarations in the project's precompiled header, so it compiles. Writing it fully qualified as winrt::Microsoft::UI::Xaml::Controls::Frame rootFrame{ }; is equivalent, just more verbose.

Closing as working-as-intended — thanks for helping keep the samples accurate, and please reopen if you hit an actual build error with the exact message.
