title: How to push data from unmanaged to managed code?
body: <p>I am using a C++/CLI Wrapper to access a purely C++ library (-> unmanaged) from a C# framework (-> managed). I want to build in a mechanism which enables the C++ library to push information about its status towards the framework. In my understanding this means that I will have to call at least a managed function from unmanaged code at some point. Is this possible and how can I achieve this?</p>
  
  <p>Many thanks for your help!</p>
  
  <p>Best regards,
  Jakob</p>
