C# UWP More information about Methods Implemetation from Microsoft

Question

Is there a way to see how Microsoft .NET methods are implemented ( eg what happened in .NET Core) or is it a blackbox?
Or are there any links to get a better understand on how these methods works, not just seeing the return of the methods?
For example the RecognizeAsync method in SpeechRecognitionResult class.

Answer 1

.Net Core itself is open source. The method you're taking about is not actually .Net Core but a UWP SDK method, which more often that not is implemented in C++/COM and is most definitely not open source. Outside of reading the documentation, understanding the method internal workings is going to be very difficult.
