@ztanczos I tried to build this directly in a codespace for this branch using 'dotnet build' and it seems the microsoft devcontainer image by default has the CLI using DotNet 7.0, so it can't build targeting net8. That said, while running dotnet --installed-runtimes I do see the .net 8 runtime present. I'm not an expert with .net but this CLI build used to work fine before. Do we need a new feature added to the devcontainer so the CLI builds the projects by default?
Or are we waiting for devcontainers/images#855 to be ready so the universal image is updated ?

Per comment added on the main PR - what needs to be done so the projects can be built by default in the codespace? (right now it seems dotnet --version returns 7.x and complains when trying to build)

@DovOps If I try using the 'dev' version of universal devcontainer then it works fine since that release already has .NET 8. Based on the conversation on the PR I believe the best would be to wait until Monday when they release to prod.

The universal image now has .NET 8:

I fully rebuilt the codespaces container, and re-ran the build and ran the services and this now works. I also ran the service via Docker-Compose to confirm that works as well.
