cant init WASAPI

    Question

    • i rewrite code of sample to my RuntimeComponent, but cant compile it in this place:
      
      m_spRenderer = Make<WASAPIRenderer>(); (in sample in Scenario2.xaml.cpp, line 471)
      
      i get error c2259, but code exactly same except UI parts.
      
      cant you give me any idea why it happens?

  • I have seen errors like that when I'm not including a required header, or including it in the wrong order.

  • order is same except i doesnt included xaml page headers - i dont use them. 

    Can it happen by reason i put this code into Windows Runtime Component (dll)?
