optional string name = 1;
}

Protoc Person.proto --csharp_out=C:\Users\Owner\.nuget\packages\google.protocolbuffers\2.4.1.555\tools Person.cs

Person.cs

public class Person

Exactly what tooling versions are you using there? If it isn't expecting the "syntax" keyword, that suggests a very old tooling version. Maybe try updating? However, the current Google tools only support "proto3" syntax. In your case, that just means changing "proto2" to "proto3" and removing the "optional". You could also try my online tooling which provides support for both the Google tools (protoc) and the protobuf-net tools (protogen) - see the drop-down at https://protogen.marcgravell.com

Unlike protoc, protogen supports both "proto2" and "proto3" syntax. There are links on the page for how to access the tools locally.
