Mono appears to be dead. I enjoy making life hard so I dont use windows. I am trying to learn very simple c# but am having trouble gettung visual studio to run anything on linux (debian/mint). It wont even run with dotnet in the terminal either. I dont really like all the features in vs either, i just want simple.

For reference im learning with the yellow book by rob miles. I want to learn the old way, not using a bunch of shiny helping tools (i never feel i really learn with those and it stunts my growth).

Depending on your distro, you may have the .NET SDK in your packages already. Debian doesn't have it. I'm not sure about Mint. I use Ubuntu MATE and .NET 8 is available. Check with this:

apt search dotnet-sdk

If you see something like dotnet-sdk-8.0 in the list, this will install everything you need:

sudo apt install dotnet-sdk-8.0

If it's not available in the package repo, it's not difficult to install manually. Follow the instructions here: https://learn.microsoft.com/en-us/dotnet/core/install/linux?WT.mc_id=dotnet-35129-website#manual-installation

For my development environment, I use VS Code with the following extensions:

  • C# Dev Kit (Microsoft) -- This provides the full development experience: intellisense, debugger, project management, etc.
  • C# Extensions (JosKreativ) -- This provides handy helpers for scaffolding classes and other module types.
  • Todo Tree (Gruntfuggly) -- Locates TODO comments in your code and displays them in a dedicated tree view.

Once you've installed the SDK along with VS Code and the associated extensions, getting started is as easy as:

dotnet new console -o HelloWorld
cd HelloWorld
code .

Clarification for Debian!

I recently installed on Debian 13 as well and these are the instructions I followed: https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian?tabs=dotnet8

The instructions say Debian 12, but they do work on Debian 13, FWIW.
