PoC gRPC using .NET

This repository demonstrates a Proof of Concept (PoC) implementation of gRPC using .NET, focusing on server-sent events. It includes both the server and client implementations, illustrating how to build and consume gRPC services for real-time event streaming.

---

Features

• gRPC Server: Handles client subscriptions and streams real-time events.
• gRPC Client: Connects to the server and processes received events.
• Server-Sent Events: Implements a streaming mechanism using gRPC for efficient real-time data delivery.

---

Project Structure

• GrpcSSE: Contains the server-side implementation.
• GrpcSSEClient: Contains the client-side implementation.
• proto: Contains the messages.proto file defining the gRPC service contracts.
