A small rpc library for using Google's ProtoBuffer services over Win32 RPC on LRPC/TCP/Named Pipes. Integrates with NTLM/Kerberos authentication.

LRPC Example

Protocol buffer ``` import "google/protobuf/csharp_options.proto"; import "google/protobuf/csharp_rpc_messages.proto"; option (google.protobuf.csharp_file_options).service_generator_type = IRPCDISPATCH;

option optimize_for = SPEED;

message SearchRequest { repeated string Criteria = 1; }

message SearchResponse { message ResultItem { required string url = 1; optional string name = 2; } repeated ResultItem results = 1; }

service SearchService { rpc Search (SearchRequest) returns (SearchResponse); } **Server-side**

//obtain the interface id for rpc registration
Guid iid = Marshal.GenerateGuidForType(typeof (ISearchService));
//Create the server with a stub pointing to our implementation
using (RpcServer.CreateRpc(iid, new SearchService.ServerStub(new AuthenticatedSearch()))
    //allow GSS_NEGOTIATE
    .AddAuthNegotiate()
    //LRPC named 'lrpctest'
    .AddProtocol("ncalrpc", "lrpctest")
    //Begin responding
    .StartListening())
{
    //Wait for connections
    Console.ReadLine();
}

```

Client-side ``` //obtain the interface id for rpc registration Guid iid = Marshal.GenerateGuidForType(typeof (ISearchService)); //Create the rpc client connection and give it to the new SearchService using (SearchService client = new SearchService( RpcClient.ConnectRpc(iid, "ncalrpc", null, "lrpctest") .Authenticate(RpcAuthenticationType.Self))) { //Create the request: var request = SearchRequest.CreateBuilder().AddCriteria("Test Criteria").Build();

    //Just call the service:
    SearchResponse results = client.Search(request);
}

```
