ServiceModel.Grpc.ProtoBufMarshaller 1.23.0

ServiceModel.Grpc.ProtoBufMarshaller

ServiceModel.Grpc enables applications to communicate with gRPC services using a code-first approach (no .proto files), helps to get around limitations of gRPC protocol like "only reference types", "exact one input", "no nulls", "no value-types". Provides exception handling. Helps to migrate existing WCF solution to gRPC with minimum effort.

ServiceModel.Grpc.ProtoBufMarshaller is package with IMarshallerFactory implementation, based on protobuf-net serializer.

Configure ClientFactory

Instruct ClientFactory to use ProtobufMarshallerFactory as default marshaller for all clients.

IClientFactory defaultClientFactory
 = new ClientFactory(new ServiceModelGrpcClientOptions
 {
 // set ProtobufMarshaller as default Marshaller
 MarshallerFactory = ProtobufMarshallerFactory.Default
 });

Instruct ClientFactory to use ProtobufMarshallerFactory for concrete client.

// client factory with default (DataContractMarshallerFactory) marshaller
IClientFactory defaultClientFactory = new ClientFactory();

// set ProtobufMarshaller only for ICalculator client
defaultClientFactory.AddClient<ICalculator>(options =>
{
 options.MarshallerFactory = ProtobufMarshallerFactory.Default;
});

Configure ServiceModel.Grpc.AspNetCore

Instruct ServiceModel.Grpc code-first to use ProtobufMarshallerFactory as default marshaller for all endpoints.

var builder = WebApplication.CreateBuilder();

// enable ServiceModel.Grpc code-first
builder.Services.AddServiceModelGrpc(options =>
{
 // set ProtobufMarshaller as default Marshaller
 options.DefaultMarshallerFactory = ProtobufMarshallerFactory.Default;
});

Instruct ServiceModel.Grpc code-first to use ProtobufMarshallerFactory for concrete endpoint.

var builder = WebApplication.CreateBuilder();

// enable ServiceModel.Grpc code-first with default (DataContractMarshallerFactory) marshaller
builder.Services.AddServiceModelGrpc();

// set ProtobufMarshaller only for Calculator endpoint
builder.Services.AddServiceModelGrpcServiceOptions<Calculator>(options =>
{
 options.MarshallerFactory = ProtobufMarshallerFactory.Default;
});

Configure ServiceModel.Grpc.SelfHost

Instruct ServiceModel.Grpc code-first to use ProtobufMarshallerFactory.

var server = new Grpc.Core.Server();

// set ProtobufMarshaller for Calculator endpoint
server.Services.AddServiceModelTransient(
 ()=> new Calculator(),
 options =>
 {
 options.MarshallerFactory = ProtobufMarshallerFactory.Default;
 });
