My Dockerfile file looks like this:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app

COPY *.csproj ./
RUN dotnet restore

COPY . ./

RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1

ENV TZ=America/Sao_Paulo
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

WORKDIR /app
COPY --from=build-env /app/out .

EXPOSE 80 5000
ENTRYPOINT ["dotnet", "Integracao_ECommerce.dll"]

Can you help me solve this problem?
