I'm using `Visual Studio Code` to write my code for Unity.
The following extension I've added to Visual Studio Code:
C#, Debugger for Unity, Unity Code Snippets & Unity Tools

Using TMPro to work with TextMeshPro components throws me this error: 

```
Unnecessary using directive. [Assembly-CSharp]csharp(CS8019)
The type or namespace name 'TMPro' could not be found (are you missing a using directive or an assembly reference?) [Assembly-CSharp, Assembly-CSharp, Assembly-CSharp, Assembly-CSharp, Assembly-CSharp, Assembly-CSharp, Assembly-CSharp]csharp(CS0246)

```

On the bright-side, in `Unity Editor` no errors are thrown, but it is still annoying.

Does anybody know if there's an additional Extension I have to download or how to fix this issue?

Best
