How to close the active sdlxliff file opened in the Editor

Hello.

I'm trying to learn the features available in the Integration API.
The first thing that I'm trying is to close the active sdlxliff file opened in the Editor.

I've created a C# project with a form containing one button.

I've added the following references:

Sdl.Desktop.IntegrationApi
Sdl.Desktop.IntegrationApi.Extensions
Sdl.TranslationStudioAutomation.IntegrationApi

Below is the code written in Form1.cs.

When I run this code, nothing happens (the active file does not close).
What am I missing here?

Thank you in advance.
