__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

frame_pool_;
auto frame_arrived_handler =

hr = frame_pool_->add_FrameArrived(frame_arrived_handler.Get(),

ERROR: hr = RO_E_MUST_BE_AGILE
It didn't work,what's the matter?
