Are you looking for a fast and easy way to create and run .NET applications using Docker containers without writing any Dockerfile? If so, you will be glad to know that Microsoft has introduced a new feature of the .NET SDK 7.0.200 that makes it possible to create and publish OCI container images directly from your project file. We have seen how ".NET 7 SDK built-in container support and Ubuntu Chiseled" can be used together. It lets us create small and secure containers for our .NET applications easily. We went from a first docker image of 216MB down to 48.3 MB. That is more than a 77% reduction in size. .NET SDK 7.0.200 bring some new capabilities. We will explore some in this post.

End of summer 2022, the .NET team at Microsoft announced two things related to containers: .NET in Chiseled Ubuntu containers and then a week after built-in container support in the .NET 7 SDK. I have talked about both topics on two episodes of the French podcast devdevdev.net by my friend Richard Clark. In this post, I will explain what those are and how to combine them.

On October 24th, Docker announced the support of WASM and WASI in a new technical preview release. I wanted to try it out and see how it works with .NET 7. If you want to know more about WASM and WASI you can read the introduction from my previous post, "Using WASM and WASI to run .NET 7 on a Raspberry PI Zero 2 W".

In the last posts, we looked at the code to build a HipChat Connect add-on with ASP.NET Core, run the solution in a Docker container and secure the access to the application with a valid HTTPS certificate that we got from Let's Encrypt for free and finally deploy all of this on Azure!
