virtual HRESULT STDMETHODCALLTYPE add_FrameArrived( __FITypedEventHandler_2_Windows__CGraphics__CCapture__CDirect3D11CaptureFramePool_IInspectable* handler, EventRegistrationToken* token ) = 0; How to use it? can you please provide me with sample code?

There is the MS sample SimpleRecorder or BasicCaptureSample or in C++ ScreenCaptureforHWND/SimpleCapture.cpp Win32CaptureSample/SimpleCapture.cpp winrt-capture.cpp

Thank you,C++/WinRT is an entirely standard modern C++17 language projection for Windows Runtime (WinRT) APIs,so I want to know how to port C++/WinRT code to its equivalent in Windows Runtime C++ Template Library (WRL) (C++11

See

Creating a minimal UWP app using the WRL
or the reverse Move to C++/WinRT from WRL

Microsoft::WRL::ComPtr< ABI::Windows::Graphics::Capture::IDirect3D11CaptureFramePool> frame_pool_; auto frame_arrived_handler = Microsoft::WRL::Callback<ABI::Windows::Foundation::ITypedEventHandler< WGC::Direct3D11CaptureFramePool*, IInspectable*>>( this, &WgcWindowSession::OnFrameArrived); EventRegistrationToken frame_arrived_token; hr = frame_pool_->add_FrameArrived(frame_arrived_handler.Get(), &frame_arrived_token);

ERROR: hr = RO_E_MUST_BE_AGILE

It didn't work,what's the matter?
