 # C API
 
-# Q: Why having a C API? 
-Q: Why not just live in C++ world? Why must C?    
-A: We want to distribute onnxruntime as a DLL, which can be used in .Net languages through [P/Invoke](https://docs.microsoft.com/en-us/cpp/dotnet/how-to-call-native-dlls-from-managed-code-using-pinvoke).
-Then this is the only option we have.

 Q: Is it only for .Net?    
-A: No. It is designed for
-1. Creating language bindings for onnxruntime.e.g. C#, python, java, ...
-2. Dynamic linking always has some benefits. For example, for solving diamond dependency problem.

 Q: Can I export C++ types and functions across DLL or "Shared Object" Library(.so) boundaries?    
-A: Well, you can, but it's not a good practice. And we won't do it in this project.
