✅ Error while Dockerizing an ASP.NET project which references another project.

So i am having an ASP.NET project called ScoreManagementAPI which references another project containing EF Core Entities Models and Context called Entities with the directory structure as in the screenshot. But the thing is when i try to dockerize the ScoreManagementAPI project with the following content inside ScoreManagementAPI/Dockerfile

# FROM mcr.microsoft.com/dotnet/sdk:8.0-nanoserver-1809 AS build
FROM mcr.microsoft.com/dotnet/aspnet:8.0.3-alpine3.18-amd64 AS base
WORKDIR /app
EXPOSE 8080
EXPOSE 8081
EXPOSE 80

# Building the core project
FROM mcr.microsoft.com/dotnet/sdk:8.0.203-alpine3.18-amd64 AS build
WORKDIR /src
RUN mkdir api Entities
COPY ["./ScoreManagementAPI/ScoreManagementAPI.csproj", "/src/api"]
COPY ["./Entities/Entities.csproj", "/src/Entities"]
RUN dotnet restore "./api/ScoreManagementAPI.csproj"
COPY ./ScoreManagementAPI ./api
COPY ./Entities /src/Entities

WORKDIR /src/api
RUN dotnet build "ScoreManagementAPI.csproj" -c Release -o /src/api/build


# Publish the application
FROM build as publish
RUN dotnet publish "ScoreManagementAPI.csproj" -c Release ./publish

# FROM mcr.microsoft.com/dotnet/sdk:8.0-nanoserver-1809 AS build
FROM mcr.microsoft.com/dotnet/aspnet:8.0.3-alpine3.18-amd64 AS base
WORKDIR /app
EXPOSE 8080
EXPOSE 8081
EXPOSE 80

# Building the core project
FROM mcr.microsoft.com/dotnet/sdk:8.0.203-alpine3.18-amd64 AS build
WORKDIR /src
RUN mkdir api Entities
COPY ["./ScoreManagementAPI/ScoreManagementAPI.csproj", "/src/api"]
COPY ["./Entities/Entities.csproj", "/src/Entities"]
RUN dotnet restore "./api/ScoreManagementAPI.csproj"
COPY ./ScoreManagementAPI ./api
COPY ./Entities /src/Entities

WORKDIR /src/api
RUN dotnet build "ScoreManagementAPI.csproj" -c Release -o /src/api/build

Anyone knows why ? please help. Also i executed the build command by standing at the Backend folder then running the following line

docker build -t score -f .\ScoreManagementAPI\Dockerfile .

docker build -t score -f .\ScoreManagementAPI\Dockerfile .

Paths inside the docker file are relatvie to the docker file itself, not to the location you are running the command from
