SayHello grpc example via DAPR

---

This is a demo project for demonstating how to use grpc client-service collaboration via DAPR

Getting Started

---

Prerequesites

To build this example you need .NET CORE SDK 3.1 installed on your computer and DAPR runtime. You can run dapr locally or in Kuberneties

---

Build

We recommend installing Visual Studio 2019 v16.4 or later which will set you up with all the .NET build tools and allow you to open the solution files.

---

Run Server locally

Assuming that you have DAPR running open command line and go to the directory with TestGrpcWithDapr.csproj. Then run the command
dapr run --app-id testGrpcDaprService --app-port 5000 --protocol grpc --log-level debug dotnet run

Run Client locally

Open a second command line, go to the directory with TestGrpcWithDapr.Client.csproj and run the command
dapr run --app-id testClient --app-protocol grpc --log-level debug dotnet run testGrpcDaprService SayHello GrpcLover

Notes

1. Notice tht we have to set a protocol parameter to 'grpc' in order to tell DAPR that we will use GRPC communication.
2. When you run the client you should set parameters for it :
   a. server name (testGrpcDaprService in example)
   b. method name (SayHello in example)
   c. message (GrpcLover in example)
