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 3, Building Entity Models for SQL Server Using EF Core, then define a contract for the gRPC service using a .proto file, and finally implement the service.

We will start with the Shippers table because it is simple. Each shipper only has three properties, an int and two string values, and there are only three records in the table. Let’s go:

1. In the Northwind.Grpc.Service project, add a project reference to the Northwind database context project, as shown in the following markup:

   <ItemGroup>
     <ProjectReference Include="..\..\Chapter03\Northwind.Common.DataContext
   .SqlServer\Northwind.Common.DataContext.SqlServer.csproj" />
   </ItemGroup>
   

   The Include path must not have a line break.
