Looks good - just a couple questions to consider before merging.

Love it! It makes the dockerfile-less builds experience for dotnet developers much better than the current status quo.
Just left a suggestion on if we wanted to update the default ports for generated infra-assets based on this change.
Good call out - I really hadn't considered the end-to-end flow for a non-aspire based .NET app via our easy-init stuff. I'll make the relevant changes and then play around with the |

The `dotnet` tool has native support for producing (and pushing) a container image. This does not require a local docker daemon and in general "does the right thing" and is the prefered way for .NET customers to produce container images. https://learn.microsoft.com/dotnet/core/docker/publish-as-container gives a good overview of how this support works and we've been using it to build and push container images for Aspire apps. This change updates things such that we can use this support when building a non Aspire based .NET app. If a `Dockerfile` exists, we respect it, but otherwise instead of trying to use Oryx to produce a container image, we will use `dotnet publish`. In addition, we now use 8080 as the default port of a `dotnet` based application (with no Dockerfile) as that's the default port used by the standard ASP.NET base image. A new recorded test was added - it builds on top of the existing `containerapp` sample, and the test aranges to remove the `Dockerfile` file from the template before running `up`.
