Myservice.proto:7:xx: "google.protobuf.Empty" is not defined.

[Tom Hintz]

New user question... Using Visual Studio 2019, C# project, I added NuGet packages Google.Protobuf and Google.Protobuf.Tools and formed a simple. I can't use Empty or Timestamp data types.  How do I reference these definitions?  Example .proto file, below. protoc.exe version 3.14.0 produces the error:

Myservice.proto:7:xx: "google.protobuf.Empty" is not defined.

syntax = "proto3";

package Myservice;

option csharp_namespace = "Google.Protobuf.WellKnownTypes";

// Interface exported by the server.

service  Myservice   {

    rpc Mymethod(Msg) returns (google.protobuf.Empty);

}

message Msg { }

You need to locate and import this file locally:

https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/empty.proto

That should do it!
