title: Is it availble to do RPC requests from server to client with gRPC?
body: <p>Foreword: </p>
  
  <p>I didn't use gRPC before. I am only taking a first look on this technology and trying to understand if I can use it in my project or not.
  I am using C# with net core 2.1, if it matters for something.</p>
  
  <p>Question: </p>
  
  <p>I have one server and multiple clients and I need to do a RPC request from a server to a client. Is it availbale with gRPC? And if so, how can I do that? </p>
