Implement CodeLens

[mirkojpn87]

C++ on VSCode

i'm trying to work on a Unreal Project, still can't activate Codelens for my project, i have the X++ extension and the c++ intellisense extension installed too...

i'm missing something?

Our C/C++ extension doesn't implement any code lens features. What sort of Code Lens info were you looking for? We can use this issue to track that. A related VS issue is https://developercommunity.visualstudio.com/idea/914294/make-codelens-for-c-show-code-changes-and-other-hi.html .

Also, I believe the C++ IntelliSense extension is incompatible with our extension.

I would personally like to see some parity between this extension and the C# and TypeScript extensions in terms of CodeLens (i.e. mainly to show reference counts for class members) — however, this extension is already quite slow in large projects like Unreal projects, so I fear at this stage adding more complexity may just bog things down even further.

This function is very useful
