How do you change Docker OS Support for a .Net Core Web Application Project?

Question

I have a .NET Core Web Application project where I chose the incorrect OS under the "Enable Docker Support" checkbox:

How do I change this for an existing project? And to be clear, I want to target linux, not "Switch to Windows Containers..." in docker.

Answer 1

This turned out to be easy, and I did it through editing the csproj file: Changed <DockerDefaultTargetOS>Windows</DockerDefaultTargetOS> to <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS> and reload.

I am still not sure where you would do this from Visual Studio (if it possible).

Answer 2

If only one project is there in the solution, I would delete the project associated with docker-compose.dcproj and Dockerfile inside the API project. After that I would right click and again add docker support to that project.

This would create new dockerfile with linux base image.

And new dcproj will have linux mentioned

<DockerTargetOS>Linux</DockerTargetOS>
