Can I use a Windows .Net app with Docker?

I'm a little confused by all the chat about Docker, and how it fits into the virtualisation world. So here's a straight question: can I package up a .Net application (that normally runs on Windows 7 etc) to run in a Docker container, and then execute it on 'any' host supporting Docker?

TIA.

A bit late, but still if it helps anyone. Yes we can run .Net apps on Docker as docker is now supported with Windows natively. But first you have to check your windows version, your windows build must be 14393.233 or greater. Download Docker 1.13.0 or later and then you can easily run a .Net App. This repository walks through running a sample .Net App.

This maybe very out of date question, but I think it need a update. Yes you can use docker with .net / .net core and will fully support in Visual Studio 2017.

The be no need to use WINE or Mono.

Not today. In future, Microsoft and Docker have announced that you there will be a Windows version of Docker.

Edit: newer info

Note that the base platform and OS have to match - i.e. today you can run ARM Linux containers on ARM Linux and x64 Linux containers on x64 Linux, but you can't mix and match. When Windows is added, the pattern will be the same - you will be able to run Windows containers on Windows OS, but not on Linux. Not without an extra layer of virtualization (like VirtualBox, VMWare, etc).

Edit: respect to the Wine answer, which I hadn't considered. It sort-of fits as "an extra layer of virtualization", but at the OS API level not the hardware level. And somewhat restricted in scope of .Net programs supported.

In a similar vein, you might be able to run your .Net code in Docker using Mono.
