Use Common Proto NuGet in C#

Question

I am trying to use a Common proto project which contains common messages used.

My project structure for the common is this. It is a .Net 5 Class library.

I then add the following in the .csproj:

It seems I followed exactly same way as here: https://github.com/grpc/grpc-dotnet/issues/183

But it doesn't work. Maybe I am doing something wrong?

I also tried import "Protos/common.proto but it did not work.
