Dockerfile should contain

FROM mcr.microsoft.com/dotnet/core/sdk:3.0 AS build WORKDIR /app

COPY app/bin/Release/netcoreapp3.0/publish/ app/

ENTRYPOINT ["dotnet", "app/myapp.dll"]

dockerfile extension has to be given as shown while running from powershell

docker build -t myimage -f Dockerfile.txt .
