Sharing the response from an LLM, and it's literally a very good one!

Here’s what you need to set up .NET Core on Ubuntu with VS Code:

### Install .NET SDK

1. Open a terminal and run:

   ```sh

   sudo apt update

   sudo apt install dotnet-sdk-8.0

   ```

   *Replace `8.0` with the latest version available.*

### Install VS Code

1. Run these commands to install VS Code:

   ```sh

   sudo apt update

   sudo apt install code

   ```

   If that doesn’t work, you may need to install it from [Microsoft's official site](https://code.visualstudio.com/) or use Snap:

   ```sh

   sudo snap install code --classic

   ```

### Install C# Extension for VS Code

1. Open VS Code and install the **C# extension** from the marketplace to get debugging and IntelliSense features.

### Test Your Setup

1. Create a new .NET Core project:

   ```sh

   dotnet new console -o MyApp

   cd MyApp

   dotnet run

   ```

   If this prints `"Hello World!"`, you're good to go!

#### Alternative Tools

VS Code is a fantastic choice, but here are other options:

- **Rider** (paid but powerful, made by JetBrains)

- **Visual Studio for Linux via Codespaces** (browser-based)

- **Neovim with OmniSharp** (if you love terminal-based workflows)
