@niulechuan Hi, thanks for the PR! I wonder if it would make more sense to change commons->shared to align more with the other examples. See https://github.com/hashicorp/go-plugin/tree/master/examples/grpc/shared.

Also, don't forget to update the code examples in https://github.com/hashicorp/go-plugin/blob/master/docs/extensive-go-plugin-tutorial.md
