How to containerize .Net project when using Shared library - asp.net

Question

So I have a .net app with file structure:
-MyApp
|__Client
|__Server
|__Shared
Inside Shared directory I have defined a model for users to subscribe.
Subscriber.cs
public class Subscriber { }
Inside Client directory, I used this shared Subscriber model.
public interface ISubscriberService
{
IList<Subscriber> Subscribers { get; set; }
}
Inside Server directory
public IEnumerable<Subscriber> Get()
{
List<Subscriber> subscribers = _unitOfWork.Subscribers.GetAll().ToList();
return subscribers;
}
Now Here's when I ran into problems.
So I needed to Dockerize MyApp project, I placed a Dockerfile inside client, although this creates a problem, the Subscriber model is in the Shared directory. Its (forbidden path) to COPY ../Shared . , nor do I find placing one dockerfile in main directory and specifing Client, Server, and Shared builds confiuration.
example:
-MyApp
|__Client
|__Server
|__Shared
|__Dockerfile
My solution facing this problem, was instead of using one docker file, was to use multiple
-MyApp
|__Client
|__Server
|__Shared
|__Dockerfile.Client
|__Dockerfile.Server
Feel like this will allow me more control, when accessing the shared library any sugestions.

SOLVED
docker-compose.yml
library:
build:
context: ./Shared
dockerfile: dockerfile
client:
build:
context: ./Client
dockerfile: dockerfile
depends_on:
- library
server:
build:
context: ./Server
dockerfile: dockerfile
depends_on:
- library
So creating a docker-compose file then telling docker directory depends_on another directory (shared library) solves it.
*EDIT
Never mind first solution seem to work correctly wonder if there's another solution where i can place my dockerfiles into the project solution rather then outside then cd into it
