How to record audio in WPF using waveIn(winmm.dll) APIs?

Question

Hi, guys, how can I record audio in WPF using windows waveIn APIs, and by using sendmessage command is not acceptable, because I have to handle the buffer by myself. Windows waveIn APIs is the only option for me, not NAudio, or DirectSound. I have tried some code, some works fine in WinForm, but they don't work properly in WPF. Can someone give me a demo code please?
