Implementing gRPC for an EF Core model

Now we will add a service for working with the Northwind database to the gRPC project.

Implementing the gRPC service

We will reference the EF Core model that you created in Chapter 2, Managing Relational Data Using SQL Server, then define a contract for the gRPC service using a .proto file, and finally implement the service:
