Open folder instead of Solution

[fschramka]

Installed product versions

• Visual Studio: Microsoft Visual Studio Enterprise 2019 Version 16.11.3
• This extension: 2.8.134

Description

If a folder gets opened instead of a solution the extension does not work.

Usecase: Project with multiple languages (example C, C++ and Scala). Instead of opening every solution (in VS and IntelliJ), just open the folder. Building is not done with VS, but a makefile.

Steps to recreate

1. Start VS
2. Open a local folder
3. Select a folder & open
4. non official VS languages don't have text highlighting :)

Current behavior

Well, in a scala file it highlightet the first 3 lines partially - but I guess this is due to keywords that are also found in VS languages

Expected behavior

Scala text highlighting like it does in a solution :)
