Controll examples are semi-working on Linux

[srdjanmarjanovic]

I have cloned this repository and used Visual Studio Code to build it with CTRL + F5.
Some categories are working as expected, some are not working at all.
The situation is as following:

• Overview
• Basic Input
• Collections
• Date And Time
• Layout
• Media
• Menus
• Navigation
• Scrolling
• Status and Info
• Styles
• Text

Here's the OmniSharp Log from output:
