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?

• the error is (sorry if something wrong, translate from russian):
  
  c:\program files (x86)\windows kits\8.1\include\winrt\wrl\implements.h(2191): error C2259: at_sound_engine::WASAPIRendererSDK: cannot instantiate abstract class (SDKHandle.cpp)

Answer 1

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

Answer 2

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)?
