In this basic setup we still only have one silo and localhost clustering, but now we have one grain and one client.
The single grain we have is responsible for greeting its clients when called:
Hello Piotr!
We have several projects in this solution:
SiloHost- responsible for hosting grains.Interfaces- this is where grain interfaces are defined. To be used by grain classes and also by the clients.Grains- this is where grain interface implementations live.Client- this project demonstrates how to connect to the silo and its grains. Two important things to be pointed out here:ClusterClientHostedService- this is a reusable client class common for most orleans clients.HelloWorldClientHostedService- to avoid basic, yet annoying problems with e.g. keeping the console alive while waiting for the cluster (of one silo) to become operational, instantiating theClusterClientHostedServiceat the right time, etc. this illustration is made a hosted service where the orleans client is provided through DI. Simple and elegant.
