How can I stay on the latest SDK patch version?

[Nefcanto]

Hello

I'm using your images for my development Docker image. This is my Dockerfile:

# https://mcr.microsoft.com/v2/vscode/devcontainers/dotnet/tags/list
ARG VARIANT="7.0-bullseye-slim"
FROM mcr.microsoft.com/vscode/devcontainers/dotnet:${VARIANT}

ENV PATH="${PATH}:/Company/Commands/ApiContainer"

ENV Nuget=/root/.local/share/NuGet/http-cache/

COPY . /Company/Infra

RUN mkdir /Temp \
    && cd /Temp \
    && dotnet new console \
    && echo '<Project Sdk="Microsoft.NET.Sdk.Web"><Import Project="/Company/Infra/DotNet.targets" /></Project>' > /Temp/Temp.csproj \
    && echo 'System.Console.WriteLine("hello");' > /Temp/Program.cs \
    && dotnet restore \
    && dotnet build \
    && cd / \
    && rm -rf /Temp

RUN apt update \
    && apt install bc -y \
    && apt install -y procps \
    && apt install gettext-base \
    && apt install apt-utils -y \
    && apt install libgdiplus -y \
    && apt install libc6-dev -y \
    && apt install webp -y \
    && apt install imagemagick -y \
    && cd /usr/local/bin \
    && curl https://getmic.ro | bash

However, when I build it, run a container from it, and enter into the container using docker exec -it container_name bash, and run the dotnet --info I see this message:

As you can see the .NET SDK version is 7.0.103.

However, at the same time, the .NET SDK version in its download page is 7.0.201.

I need to stay on the latest patch update. How can I do that?

Hi 👋

The .NET images are dependent on the upstream mcr.microsoft.com/dotnet/sdk images. That said, our dev tags have been updated with latest .NET version v7.0.201 - reference.

In the meanwhile, feel free to use mcr.microsoft.com/devcontainers/dotnet:dev-7.0 in your Dockerfile. I can help release the images today/tomorrow which will update the prod images.

@samruddhikhandale thank you for answering.

The problem with the upstream image is that it does not work for debugging in a container.

We tried that several times and we could not make it work. Maybe you have added extra stuff that makes it possible.

We need to be able to debug inside containers using the Dev Containers extension.

And I'm grateful that you are doing this update. However, I'm not asking about this one instance. I'm asking in general to see what options do we have, to always stay on the latest SDK release.

[samruddhikhandale]

We do have a monthly release cadence for all the images, which happens in the first week. Besides that, we have in between releases depending upon patches and bug fixes. However, if we have an issue asking us to release an image to update it, then we are happy to take such requests as well.

For major version releases, let's say .NET 8 is released, then we support it immediately. Look at the tracking issue #90 for more details.

@samruddhikhandale thank you for the detailed answer. So we can stay sure that we won't stay behind Microsoft for more than a month. That's very good. Thank you.

Closing as .Net images are updated 🚀
