### Describe the bug.

I can't install .NET, I tried it when I come to Github for that.

### Reproduction Steps

Install Unity(6000.2.8f1), then make and open a script to vs code.
Make sure you have the C# Dev kit and Unity on your VS Code extensions.
Try writing a few lines, it should question about not being able to install .NET, That's where you'll click "Get the SDK".
It loads a minimalist UI to install .NET 8.0, Click Install.
NOTE: it is most probably hard to reproduce and might need specific conditions i have no idea about.

### Expected Behavior

It should obviously download and install its desired .NET version.
