Multi-Targeting .NET Framework & .NET Core

[RehanSaeed]

Steps to reproduce the issue

I'd like to be able to build my project targeting .NET Framework and .NET Core.

Expected behavior

A docker image exists with both the .NET Framework (Mono) and .NET Core.

Actual behavior

No such image exists.

Additional information

I was not certain where to raise this issue but I thought I'd get the ball rolling here. I''ve also raised an issue in the mono repo here.

I've also raised a similar issue here in the aspnet/aspnet-win-docker repo to add a similar image for the windows containers.

FYI - the .NET Core SDK itself does not support targeting .NET Framework on any platform but Windows. dotnet/sdk#335.

I've also raised a similar issue here in the aspnet/aspnet-win-docker repo to add a similar image for the windows containers.

This is the repo to use for both Linux and Nano Server containers for ASP.NET Core.

Yes I'm aware of that, you can still get it working with Mono with a bit of work. It becomes more important when the feature in your linked issue is implemented.

Having a Windows image with .NET Framework and .NET Core would still be useful.

Since we don't have an image for this today, you will need to build your own. You can probably do this by combining elements from the following images:

https://github.com/Microsoft/aspnet-docker/blob/master/4.7/Dockerfile,
https://github.com/dotnet/dotnet-docker/blob/master/2.0/sdk/nanoserver/amd64/Dockerfile,
and https://github.com/aspnet/aspnet-docker/blob/master/2.0/nanoserver/sdk/Dockerfile.

Or, consider using a multi-stage build using microsoft/aspnet and microsoft/aspnetcore.

Closing in favor of dotnet/sdk#335. Docker isn't the right layer for adding support for this.
