migrate from mcr.microsoft.com/dotnet/core docker base image to mono:latest docker base image

[iceagebuck]

my application has been built using mcr.microsoft.com/dotnet/core docker image. Now we are planning to use mono instead of dotnet to make it cross platform compatible.
It would be great if someone can help me with example(Dockerfile) or redirect to resource which I can refer to perform this migration.

Current Dockerfile

`FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build
WORKDIR /app

COPY *.csproj ./aspnetapp/
WORKDIR /app/aspnetapp
RUN dotnet restore

WORKDIR /app
COPY . ./aspnetapp/
WORKDIR /app/aspnetapp
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2 AS runtime
WORKDIR /app
COPY --from=build /app/aspnetapp/out ./
ENTRYPOINT ["dotnet", "Sample.dll"]`
