Client factory

gRPC client factory can be configured to use load balancing:

• Configures the client with a load-balancing address.
• Specifies channel credentials.
• Registers DI types with the app's IServiceCollection.

var builder = WebApplication.CreateBuilder(args);

builder.Services
    .AddGrpcClient<Greeter.GreeterClient>(o =>
    {
        o.Address = new Uri("dns:///my-example-host");
    })
    .ConfigureChannel(o => o.Credentials = ChannelCredentials.Insecure);

builder.Services.AddSingleton<ResolverFactory>(
    sp => new DnsResolverFactory(refreshInterval: TimeSpan.FromSeconds(30)));

var app = builder.Build();
