Question

I am trying to containerize in Windows Container a .net framework 4.5.1 MVC application. I created a template application as VS creates it , without change anything. I publish the app and tried on my windows locall iis server and runs ok. Then i tried to put in container with the following Dockerfile:

    # Build stage
FROM mcr.microsoft.com/dotnet/framework/sdk:4.8-windowsservercore-ltsc2019 as build
COPY . /app
WORKDIR /app 
RUN msbuild netapp451.sln /p:Configuration=Release /p:OutDir=C:\app\bin

RUN dir
WORKDIR /app/bin/

# Runtime stage
FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019 as final

COPY --from=build /app/bin/ /inetpub/wwwroot

EXPOSE 80 

The image successfully builted. I run it with docker run -d -p 8082:80 test4511. in my browser i enter HTTP://localhost:8082 and i get
