Come learn about new features in the .NET CLI coming in .NET 10 that enable directly running a C# file without the need for a project, with a smooth grow-up path if you decide project features are required.

On “.NET 10, IntelliSense in VSCode, Linux Mint.”
Thanks for the answer. I asked because in the official presentation five months ago (link to this video , starting at 2:35), IntelliSense, including syntax highlighting, was working. I just wanted to find out whether there’s an issue with my specific setup or if it’s a general problem.

On “An Agent in a File”
Thanks! Maybe there is some confusion? There is already support for publishing as a single file, but what's coming in .NET 10 is actually just being able to define your app in a single file without worrying about a csproj file. There is a pretty good GitHub issue here that is tracking the progress and references a lot of related content.
